Hi Sir,
Thank you for giving knowledge sir.
how can i get different client systems mac addresses in a web application using java with browser compatability
i tried to get different client systems MAC addresses who are accessing my application…but i got only one address MAC (server system) all the time..
below code:
InetAddress ip = InetAddress.getLocalHost();
Enumeration networks = NetworkInterface.getNetworkInterfaces();
while (networks.hasMoreElements()) {
NetworkInterface network = networks.nextElement();
byte[] mac = network.getHardwareAddress();
if (mac != null) {
System.out.print(“Current MAC address : “);
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
sb.append(String.format("%02X%s", mac[i], (i < mac.length – 1) ? "-" : ""));
}
System.out.println(sb.toString());
}
}
output: single MAC Address ( server system MAC Address)
But the problem is i want different MAC address of different client systems who are accessing my application n…will you please help me..

I am referring your blog since months and i think you are doing an awesome job.
I would like you to put something on Remote Method Invocation !!
Thank You.
You pointed out very correctly. I will do it within a week.
I can give a brief introduction on RMI. Invoking a method existing on a different system, existing anywhere in the Globe, from your system without using Internet is known as Remote Method Invocation. For example, to know your account balance from ATM center existing in a bank server which is generally in a different place.

Dear Sir,
I really appreciate you for your great work. I’m the great fan of you & I always suggest to my friends to read your book. I read your core Java book 2 times which help me a lot to understand the core Java concepts clearly.
I’m 2014 pass out MCA student, working in a small company in Kolkata as a Java programmer. Right now I’m working on an ERP project which uses Java technology like struts framework and JDBC. Before that I worked in a part of this ERP project which is developed in Spring & Hibernate technologies.
But sir, my problem is I’m getting very confused working on this project as I’m newbie on the above mentioned Java technologies and not getting properly. Could you please tell me in which institute of Hyderabad, I will join for online training for Spring, Hibernate & struts ?
Contact either Peers or Durga.

I prefer to say through Institute.

Sir,
I have been a regular follower of your site way2java.com I am a huge fan of your posts. I have also recommended your site to various friends and of mine. I have few doubts and wish to seek your help and guidance.
Sir, I am 2014 pass out. Now I wish to start my career as a Java/J2EE Developer. I am well-versed with core and advance java. But due to cut throat competition in IT field, I am not able to get job as a java developer. After complete research on internet and discussions with seniors and I have decided to make a 1 year fake job experience certificate because that is the ongoing trend in getting jobs.
Sir, I wish to know with what technologies should I equip myself so that I can be as skilled as a person with one year of experience is. Please suggest me which java technology should I must learn. I will also wish to know in what companies should I apply so that there is no background verification.
I would be truly grateful if you could clear my queries.
Thanking You.
Regards
One year experience is not treated as experience, it should be minimum 2 years. Experience guy means he should have minimum 2 years experience. Below 2 years, it is treated as fresher.
Then what to learn depends on the project you put. In general learn, Spring, Hibernate, some testing, Struts etc.
there are lot of companies in delhi/ncr which hires 0 to 3 year experience programmer..!!
Please tell me what should i do..!!
should i join any insititute that provide live project training?? or should i learn everything myself?? Please guide me in details..
I have also sent you the same email you may guide me out there. my email address is [email protected]. I have sent an email to [email protected] 1 month ago.
Do not learn yourself, it is time consuming. Join some institute.
Ok sir :)
Thank you for your valuable comments. One more thing I wanna meet once in my life… whatever i learned i learned from here only. Thank you so much.

sir
i have doubt about webserver and application server.
on which scenario we have been go for webserver and application server.
and what are the main vary between webserver and application server sir.
please reply sir.
Application server executes applications – any applications. For example, Weblogic is an application server that executes J2EE applications. A web server executes only web applications like Servlets, JSP and Struts etc. That is, a web server is an application server that executes only web applications. Sometimes, as with Weblogic, an application server can also be a web server.

Hi Sir,
What is the difference between Struts2 and Spring framework ?
Struts is MVC framework. The same MVC framework is supported by Spring. That is, now Struts can be done with Spring framework integrated with Hibernate. The added advantages are transactions.
i am doing java in hydrabad.whats is future in jquery and ajax?
and what about the future in informatica
jquery and ajax, by themselves are technologies, they are used here and there.
If you are a fresher, Informatica is not required at all.
As a m java developer it is required to learn pega tools for faq experience.
Depends on the projects you have projected. Like Pega many exist like ADF Java. How many you can learn like this?
okk.but sir,what about the tibco tool?
it ie required for all the project or not?
okk.tell me the common tools that required for puting some faq expe.
TIBCO is a integration tool of different modules (or business processes).
General tools:
IDEs: Ecplise, NetBeans
Web Server: Tomcat
Application Server: Weblogic, JBoss
hello sir
sir please suggest me i fresher there is lot of problem to get the job i am completed full pkg of java.. so any other course will benefited me or not please tell..
if yes then which cousre??/
Nothing more you do. Be strong in what you learnt and try and try jobs. On one day you will definitely get job. Read what you are lacking in the previous interview.
sir,what are the future of informatica?
i am doing java.if i put 1.5 years exp is it required to learn webservice?
and for the struts is required b/z all are sauing now days no company used struts b/z of spring.
You are right, Struts can be done with Spring MVC and the same with EJB also. Web service is an added advantage for your resume.
okk.it is required to learn ejb also…
sir it is required to learn as a java developer for ADF oracle…
if i learn it will benefited or not?
ADF is not used everywhere. I have seen Accenture is using ADF.

thanks for yure reply…
If you are fresher of B.Tech. batches 2013 and 2014, all these are not necessary. If you keep fq experience, then some of these are necessary. Which are necessary of these? It depends on the realtime experience projects you do?
i am putting experience with 2.5 exp…
so plz guide me except java another which course help me to get easily jobs..i am confused b/z i did 8 months but no use..
so is there any other way means another technology?
i am very happy to see yure materilas.i have one question ,i want to do webservice .which is the best in hyd?
ActiveNet. Lecturer: Mr.Suryanarayana
i want to do all java tools in hydrabad.which is best faculty or notes are available.
All are not taught by one person. First contact Mr.Suryanarayana of ActiveNet. He teaches some tools and enquire from him for other. Anyhow, learning all is laborious and time taking. If you are employed, learn those you are using in the work. If you are fresher and seeking job, learn Weblogic, JBoss. If you keep fake experience, the best tool is TIBCO and is easy to master it. Many jobs are available throughout the world on TIBCO with 3 years experience. Try and anyhow take second opinion.
sir,i am java developer.Is it required to learn tibco b/z all are saying its not java developer jobs to learn tibko tools.its only for testing worker
If your job does not want, do not learn TIBCO. Concentrate more on what your job require.
sir, i meant to say that it is required to learn tibko if i am work as a java developer.
which tools mostly used as a java developer in an industry?
JBoss, Tomcat servers,
NetBeans, Eclipse IDEs
i meant to say that tibko used for testing purpose.
can java developer have yu work on tibko tool?
TIBCO is not for testing. It is business process integration tool.
ok… i got it..
but in ameeepth all are teaching maven ,svn tools.
no one teach this type of tibko tools..
Sir,if you know else yu are teaching i am ready otherwise suggest me another institue in ameerpeth.
For TIBCO, contact the expert [email protected] at Hyd.
He will teach TIBCO, gets you one or two realtime projects also. Give my reference as S.Nageswara Rao, Java Trainer.
ok sir… plz tell me the what are the tools are equired to put 4 years experiance//
is it required to learn tibco.
You know 4 years is very long time where you should be very pre-cautious in interviews. Do some realtime projects from start to finish (upto deployment on client machine). Take guidance. Get acquainted with problems you encountered in coding and how overcame, design patterns used in the project, Struts, Spring, Hibernate is a must. Tomact web server, Weblogic application server, JBoss application server, Eclipse and NetBeans etc. Have command over XML like XSLT, XPath etc.
Hello sir,

Actually I am not sure. Now and then I here, but I do not remember. Take feedback from old students (coming out of the institute, wait outside) and then join.
Hello sir, i know this not the place to ask such Q, but still i want ask u that does degree or percentage matters after getting experience in IT world??
I have 2 year diploma in software engg and graduation degree (BA) right now i am working in a small product based company as trainee java developer. i m also doing mca from IGNOU, i fear sometime that it will affect my career in future reasons are:
I don’t have good score in academics nor in graduation.
i don’t have good degree but still they selected cause of my knowledge still i am very scared about my future. Working as Corporate Trainer on Java you must have knowledge about this. the main what Q is what matters a cool degree or experience in java world???
i want to tell you one more thing that i didn’t learn anything in my institute whatever i learn i learn from this site only.
Thank you very much sir.
please clear my doubts..
Do not think any other thing. First complete your MCA through IGNOU. Put 3 years of experience. When you complete 2 years write me, what you should do in 3rd year.
Do not worry about future. It will be bright. Concentrate on coding much. Read computer dictionary available in the market.
Let me know your place of work, is it Hyderbad?
Ok sir. :)
No, working place is Delhi.
Sir actually i am in 2nd sem so after completing MCA i will have 2 years of experience.
How?
Sir, I couldn’t understand! How can i put 3 years experience when i only have 2 years?? and if i put fake exp then what if they will surely check my background ?
is there any company which provide genuine experience certificate?`
It is not possible to keep 3 years experience when you have only 2 years gap.
Hi sir,
sir why set contains unique elements? This Question was asked to me in
Accenture interview. Could you Please tell me the answer.
Thanks & Regards
Adi
It is designed like that to accept unique values. To have duplicates, List is there.
sir,i am putting 2 yers faq experience..sir,i am confused in which one is mandatory.
jsf is best or struts..which i prefer .
Struts
Hello sir,
please tell me the meaning of this line – Super d1 = new Demo();
abstract class Super{
public void display(){
System.out.println(“From abstract class”);
}
}
public class Sub extends Super {
public void display(){
super.display();
System.out.println(“From demo class”);
}
public static void main(String[] args) {
Super d1 = new Sub();
d1.display();
}
}
As display() is overridden, d1 calls Sub class display() method. From Sub class display() method, you are calling Super class display() method.
Rule: When a subclass object is assigned to super class object, the super class object will call subclass overridden method.
Hi sir,

Respected Sir,
I am a big fan of yours.I have read your book Core Java.An Integrated Approach….Its out of the world….Its the best book in java with such clarity of conception…..Sir you bgreat….And here you are doing a great job Sir…Thank you Sir for guiding so many of us…….
Hello Mr. Nageswara,
First i must say your explanations are quiet understandable and are approaching the subject from whole different perspective (different than standard teaching patterns) which makes it easier to realize and understand.
Actually i have a simple question where i can’t find answers for.
ObjectName obj = new ObjectName() ;
Why does the reference variable type matter in java?
I mean it (reference variable) stores just the reference (8 byte) number that points to the register where the real object lives. Why wants java us to define the reference variable type? It could store the 8byte address anyway even if we don’t define the type. Thank you.
Do not bother about 8 bytes not. Reference variable concept much useful in case of interfaces.

If you do not worry about time of completion, best is ActiveNet, Suryanarayana. He has got a habit of not coming to class without information. If you can bear this, he is the best.

Sir, please answer me as soon as possible.
Q) Print the value of Pi (22/7) upto 100 digits after decimal point with ten digits in each line. (AMAZON interview question)
My approach in C,
Observed the pattern repeats for every 7 digits after decimal but this is not completely implemented. Output is also given.
int main()
{
double pi = 22.0/7.0;
int x=1;

Thankyou sir.
Join some institute teaching Java to a good extent. If you are at Hyderabad, I can suggest, other places I am not aware of. It takes minimum 4 months. It requires lot of practice. Think you can spare that much time along with regular subjects.
gd evg sir …..
i need complete explanation about transient variable?
See this link:
http://way2java.com/serialization/java-serialization-example/
A variable declared transient is not serialized. To know the difference, do a serialize program, declare one variable as normal and the other transient. See the difference in the output. The value given to a transient variable is not seen in output. Try one example and find the answer yourself, then you will be more satisfied.

Your program is working nice. The possible problem with you is, you have saved the file in one directory and compiling from different directory DOS prompt.
Write always like this to avoid this type of problem:
C:\snr> notepad Demo.java
Do not write
C:\snr> notepad
like this and save afterwards.

Suggest me which one i choose .If i chose java which technologies i have to learn

If you know Java earlier, learn Struts, Hibernate, Spring, log4j etc. required for realtime programming.
Sir,
Thank you very much for this wonderful website and your time to respond our queries.
I am core Java developer with 2 yrs experience. I heard that Big Data is having huge scope in future and the sources for big data like Hive, Hadoop have been developed using Java. Is it good to switch that side? Does really Big Data contains Java concepts. Please advice me.
Thankyou
Abhinay.
Think of shift when you draw less salary. Java comes with many tools and applications. To what you can shift like Hadoop, BigData, TIBCO, WebMethdos etc. Learn when it is required only or you find a vacancy in that field.
Sir,
I have 2.5 years experience in adv java and hibernate. As because of my marriage I have 1 year gap. Now I want to continue my job as either developer / tester or is there any other option?
Suggest me which one is good for me to have long career in IT sector and also suggest me, do I need to do any certifications. Kindly clear my doubt. I am in a very big dilemma.
Go as developer without second thoughts. I know many testers having good experience to shift to developing. 1 year gap fill up somehow.
Sir,
I am very happy to meet you through this site. I have 2.5 years experience in java technology and i am B-Tech 2010 passout. As because of my marriage, I resigned my job and came to abroad. Now we are moving to Hyderabad on this September and I want to continue my job.
I feel testing is good for married women to continue their job for long time. Suggest me what I have to opt? If testing is fine, can I get some good job with my past experience?
When you come to Hyderabad, meet me with your husband. We will discuss your future course.
Sir,
I would like to appear for OCJP examination and how would you suggest me to prepare myself on exam.
It is three level process.
First answer the basic questions I have given in way2java.com. There 8 questions papers.
Secondly, go to web sites read and practice.
Thirdly, do some mock tests.
When confident, write the exam.
i am doing mca and i want to do hibernate and struts course with projects so i will be prefect in both.so plz suggest me the best trainy institue in ameerpth .
For Core and Advanced Java, it is Durga Software Solutions, Maitrivanam, Ameerpet. Contact:040-64512786.
For Hibernate, Spring and Struts, it is ActiveNet, Ameerpet, by Surayanarayana. These things you require very good practice and dedication. You must have good understanding of JDBC, Servlets and JSP. Better to have Oracle also.
sir i am doing mca and i am here in hydrabad to leran selenium tools.
i know core java very well and …
what about the pre requisite for this selenium tool and what about the future.
Some testing knowledge and Basic Java is essential. Ant script and XML are also required and they will be taught in the course itself.
sir, i completed mca in 2014.what about the future scope in android ..
it is good or not.
i know core java ,adv java,spring,struts.it is helpful for me.
which institue in ameerpeth teach nice
Android is good but its salaries very less comparative to general Java programmer. Programmers are there working for Rs.20,000 salary having 3.5 years experience.
How can we use both PrintWriter and ServletOutputStream in servlet with response.
See this link:

Hi Sir,
I am Srilatha 2009 b.tech graduate and i have total 3 years of testing experience and i resigned for my job in 2013 jan as i need to accompany my husband for his onsite.So i was staying in abroad since one and half year which is a career break for
me.And i have started learning java since two months and planned to complete advance java through online training so can you please tell me what would be the scope for getting job in java technology when i return to india.Do the recruiters consider my profile.I am very much interested to migrate myself from testing to java technology. Do you think its good to show some fake experience on java(for this one and half year gap).. please suggest me..
Yes, you can have fake some period as you have got some realtime experience earlier. Come to India on testing only. Afterwards, we can think of migrating to Java.
Online training is not effective as class room teaching.
When you can return to India as per existing plan. Can you not get job in abroad on testing?

The prerequisite is some database knowledge and Java.
Go for all these if you are keeping some experience; for fresher not required at all.

Sir’
Can we use System.in with servlet page?
if yes then how??
System.in is used to read from Keyboard. On server-side nobody sits to take input from the user. So, no body writes. The same System.in data you can keep in.
By rule you can keep it. It does not have practical implication.
Respected Sir,
I am 2013 m.tech passout and 2010 b.tech passout and i learned core java and adv java from durga institute. I tried in so many companies as a fresher but did not selected.My friends guided me that put 2 years of fake experience in java and 2 years of fake exp. in Hadoop technology.One other option i am having that i can also put 4 years of experience in java technology.So please guide me sir which option will be good for me.I really confused.
Waiting for Your Favorable reply.
Thanking You
Regards
Praveen Srivastava
First one 2 + 2 is preferred.
But remember, for fake you must prepare too depth in subject more than with real person. Do some good projects with design patterns, frameworks like struts, hibernate and spring.

Respected sir,
Please explain the mechanism of servlets and web container?
I mean Architecture of Servlets explanation.
Servlets has no main() method then how methods of Servlets are called ?
Even applets do not have main(). All methods of applet and servlet are callback methods.
Check this:
http://way2java.com/servlets/servlets-introduction-tutorial-and-architecture/
Respected sir,
Thank you very much sir for your good service.
Why we say a component is a reusable software? In this context,Reusable means?
What is difference between server-side component and web component?
Suppose you got an electrical extension box. Can you call it is reusable? Yes, you can use whenever you would like for supplying power to a light or washing machine etc. I call extension box is a reusable component. Component is does not require any modification for reusability.
A server-side component means a software component (program) that works always on server-side. What is server-side? Suppose you you booked a railway ticket with waiting list. You want to know the status of your ticket now and then. You enter the PNR number and click submit button. Now there should be program on server-side to take your PNR number and get you status. The program which works on server to fetch your ticket status is known as server-side component. Then here, what is client-side? The client-side is a GUI where you can enter your PNR number.
A web component is a server-side component which uses Web (Internet) as a conversation point (or interface) with client. Do not think all are Web components. suppose you go to a bank ATM to get balance of account. There you do not see a browser. The interface is not Web. So, do not think all are web components in the world.
Respected sir,
Thank you very much for your clear explanation.
What I understood from your explanation is :—
Component is a software unit.
Reusable component is a software unit can use anywhere when it needs in any program E.g.,Buttons,Text box,.. which are predefined(built-in) components which can reuse anywhere.
Server side component is a program which resides in server and executed in server but here client/server can use any medium(interface) for communication.
While in the case of web component,web component is also server side component but client/server communication uses web as interface for communication,that is web browser as interface.
“””If I am wrong anywhere,please assist me.”””
Sir,What are the other various means for communication except web browser?
Thank you very much for such a patience.
God bless you sir.
Web is the interface. Web browser is not an interface. Web browser is the software required on the client side to send a request to the server.
Respected sir,
Then,what are the other softwares which are used to send request to server except web browser?
Nothing is required except a browser and Internet connection.
In simple words,What are Servlets ?
Servlets are server-side Java programs used in web communication.
Please,Explain mechanism of Servlets and web container?
In Servlet program,there is no main() ,then how methods in servlets are called?
Respected sir,
Can I ask you(sir) about IEEE project doubts?
No please.
Sir,
What is the difference between Class variables and Instance variables?
class variables are static variables and instance variables are non-static. Static variables do not require and object to call and instance variables require.
Thank u very much sir.
you are helping alot of students inspite of your busy schedule.
God bless you sir.
hello sir…
I am confused with the concept Polymorphism….Will you plz explain Ploymorphism (Why,Where to use,How to use..?)
thx…!
http://way2java.com/java-questions/object-casting-and-polymorphism/
Read the above link and ask me further doubts.
Sir, When i execute the below code snippet
public class Demo
{
static double $rate;
static int noOfDollars;
static
{
$rate=63.2;
noOfDollars = 3;
}
public static void main(String args[]) {
System.out.println(“I am main() method and will be calles after static method”);
System.out.println(“The value of $rate is :” + $rate);
System.out.println(“The value of noOfDollars is : ” + noOfDollars);
System.out.println(“The conversion value is :” + $rate * noOfDollars);
}
}
Output:
I am main() method and will be calles after static method
The value of $rate is :63.2
The value of noOfDollars is : 3
The conversion value is :189.60000000000002
But when i execute the same code by removing static for variable initialization
block like below :
public class Demo
{
static double $rate;
static int noOfDollars;
{
$rate=63.2;
noOfDollars = 3;
}
public static void main(String args[]) {
System.out.println(“I am main() method and will be calles after static method”);
System.out.println(“The value of $rate is :” + $rate);
System.out.println(“The value of noOfDollars is : ” + noOfDollars);
System.out.println(“The conversion value is :” + $rate * noOfDollars);
}
}
Output is
I am main() method and will be calles after static method
The value of $rate is :0.0
The value of noOfDollars is : 0
The conversion value is :0.0
Could you help me in understanding the difference??
Variables are initialized in static block and later used by the remaining part of the code.

Sir,i want to more practise in collection and exception handling and many more
sir,plz suggest me how can i learn more programs?
Just google and no other alternatieve.
sir iam feeling good and comfortable with the concepts of core java but iam lagging in implementation.iam very weak in developing logic.iam very much interested in learning java.plz advice me how to get rid of this problem.
Do a small project and it gives you an enormous confidence.
public static void main(String[] args) throws Exception {
int res = ToolRunner.run(new Configuration(), new EchoOhce(), args);
System.exit(res);
}
i cant understand this step , please explain
ToolRunner.run(new Configuration(), new EchoOhce(), args
ToolRunner is a Java class. run() is a static method. The parameters of this method are 3 objects:
1. an object of Configuration (for which an anonymous object is of Configuration is passed).
2. an object of EchoOhce (for which an anonymous object is of EchoOhce is passed).
3. an object String array for which args is passed.
For anonymous objects refer:
http://way2java.com/oops-concepts/reference-variables-anonymous-objects/
Sir you are truly made for JAVA… Your way of understanding the concepts and examples are very great….. thank you so much for helping via this blog….
Sir I am very much interested in java. I have knowledge of concepts but i don’t have programming logic.
plz guide me..what should I do to develop my logic?
With Java, you cannot increase programming skills because everything is given in the form of API methods like class Arrays and class Collections etc. Programming skills will be improved in C-lang only. Try practising C-lang like prime, even and odd numbers etc to start with.
Hi This is good site for java
Sir,
First of all i should admit that its the first site i noticed where the author is responding to each and every question that has been put up. My heartfelt regards for it.
Secondly, Im learning SELENIUM. Can you please tell me its CORE JAVA concepts enough for usage in selenium commands. If yes, Do you have a precise notes or material exclusively for CORE JAVA.
Any help will be deeply appreciated.
Thanks in advance.
There is no separate and precise notes on the Core Java required for SAP Netweaver, Android and Selenium etc. Pick the required concepts and practise. Many tools takes care of implicitly threads managements (so, not required much of thread practising but concepts are required for better understanding), in file management read file copying using BufferedReader and BufferedWriter and not required much deeper, learn OOPs much deeper and there is no compromise in it, AWT GUI is no required at all, networking is not required, exception handling is required in total etc. Check the documentation of Selenium, you will have better understanding on what is required.
Sir Please tell me what is the actal difference between Wait() vs Sleep() vs Yield() in Java in which situation which to be used

Hi Sir,
What is the difference between throws and thrown in exception handling?
You mean throws and throw:
These two keywords are used with exception handling. “throws” is an alternative to try-catch but not robust way.
http://way2java.com/exceptions/throwing-with-throws-alternative-to-try-catch/
“throw” is used by the programmer to throw an exception explicitly to the system. Generally used with user-defined exceptions.

hi sir,
please solve this problem.
3. Write a Java program to list out the first 1500 natural numbers whose factor(s) is/are either ONLY 2, 3, or 5. The faster your program can complete the calculation the better, but it should not run more than 2 minute.
For your reference, the first 20 numbers are (factors listed after semicolon):
2 : 2
3 : 3
4 : 2 2
5 : 5
6 : 2 3
8 : 2 2 2
9 : 3 3
10 : 2 5
12 : 2 2 3
15 : 3 5

30 : 2 3 5
32 : 2 2 2 2 2
36 : 2 2 3 3
40 : 2 2 2 5
PS: 21 (3*7), 22 (2*11), 26 (2*13) are numbers that should not be in the list.
This type of problems to solve, I do not find time. Now Hibernate postings are going on.
give some logic sir….
find the factors of each and every number and store factors in array.Then check the array wheather it contain numbers other than 2,3,5.
code should be like checking is to be done for each number and take another array to store them………..
Calculate the factorial of each and every natural no. and store those factors in array.
Take another array to compare whether it contain the numbers others than the 2,3,5.
Calculations to be done for each and every number individullay……….
give me some logic sir
Here is a sample code for your question..
You can improve the code to fulfil your requirements

Good morning sir,
This is praveen kumar so i’ve small doubt sir,i.e
i wrote registration form jsp and after that i’ll create a database in mysql after that how to connect jsp to mysql

Simply write JDBC steps in JSP scriptlet. A better advise is use JavaBeans for database connection.
sir, my first qus. is suppose in one .java file 3 classes a,b,c are there and among them only class b is public, so we have to save this java file as B.java and compile it using the name of class B,so what is the reason behind this?
and my second qus. is why java.lang pkg is by default available to all java classes and how?? why not others like java.util and java.net etc. pkgs are available bydefault to every java classes??
Compilation starts from public class.

An abstract method cannot be final. But final concrete methods can exist in abstract class.

Simple way when no Internet is there:

For example, if you would like to know the methods of String class:
c:\snr> javap java.lang.String > aaa

i am confisud what i do java or sap…
sir please guide as a growth level sap is best or not?
one thing sir,i m doing mca in pune if yure treply java where i have to go with providing placement.
and sap then tell me the institue that gives knowlwdge and placement also.
thanking you
Growth is same in both. But salaries are high on SAP but at the same time getting job is very difficult as opportunities are very less. But freshers, SAP posts will not be given at all. For this reason, many people join SAP with fake experience provided they got gap after completing B.Tech. Java gives chance for freshers and at the same time, openings are many. Now it is your choice.
sir i have not seen this type of content in other web site also your unbelieveable sir i need struts1.x,2.x and also hibernate notes sir can u plz arrange or tell links .
because in other websites there is not a understandable data.
Tell your friends to derive knowledge of this web site. For Advanced Java, Struts etc, it takes a very long time.
I do this site with passion. I got very many activities to do.
Hi Sir,
I have gone through wrapper classes concept. It is clear and easily understandable.
Thanks for providing such a good explanation with simple examples.
sir, can you please explain about looping and how to store value in variable when sorting is done ??
Hello Good Afternoon Sir,
I have completed corejava and Advance java and going to start Hibernate and Spring so which faculty is teaching well?
As i am 2012 BTech passout ,
so howlong can i try as a fresher?
Is Struts necessary to do ?
What is the difference between Java and .net ?
Sir please comment…
a) The best institute is Active Net (Faculty: Suryanarayana) and must have some patience to attend his classes.
b) You can try as fresher upto maximum 2014 April.
c) Struts is required for fresher.
d) Spring and Hibernate are not required for fresher.
e) Java and .NET are parallel technologies. .NET is used in small applications and Java in big applications due to high security support, many say.
Good morning sir,
I have completed Core Java,Advanced Java(Servlets, JSP)…Now i want to learn advanced course..
Why struts is required for freshers???why not springs and hibernate?
Exactly speaking, Struts is not required for freshers. If it is the case, many other also remains like Hibernate, Spring, Web services etc.
Hi Nageswara Rao,
Today i have used this tutorial .It is looking awesome .Really Good . Could you please post spring and hibernate .it could be helpful for us .
Thanks
Iyappan
Hcl Technologies
Still I have not posted advanced Java like JDBC, Servlets etc. It takes sometime. way2java.com is a hobby to me and not the profession. It gets you Java without even asking your name or login.
I develop it in my spare time, if available.
Thanks for your complement. Tell your friends also to go through to derive knowledge. I want to prove always Java is simple to practice.
Hi sir

it is really vere helpful site for the freshers thank you to mr.nageswar rao for providing to us a gud site
HI Sir,
i am based out of Hyderabad. is there any way i can avail your coaching classes.
Not possible. I won’t teach online.

Definitely it is Java. On Java, you place anywhere in the world, Jobs will be awaiting you.

It is 45 days each.
Hello sir,

It is Java. Do get jobs in Java is easier than SAP. Go to any part of the world, you get a job on Java.
i’m studying B.E 3rd year CSE 5th sem.i want to join in software company with best salary.whether i will have need to learn any other course.please tell
Yes, a lot. First learn C-lang very perfectly. Then Java also perfectly. C++ knowledge is preferable. One database like Oracle.
Also aptitude and reasoning, English.
All these are very much required to acquire a job. Do not think you know all these from your college curriculum. Your college curriculum is useful to get marks not job. Join in some good institute and start learning, practising, it is the good time for 5th sem.
Java stores object on heap and variables on stack. For the explanation of heap and stack, refer some web site.

Learn Java. Learn Android (it is Java based mobile applications). If you are very good at subject, small companies will take you. After 3 years, you can shift to big companies. It is the easiest route for you to enter software field. Meantime, you can do MCA (IGNOU).

Thank you sir for all your tutorials…..

Mehidipatnam does not have good teaching institutes. Then go for Ameerpet like InerSolve (Inetsolv, Satya, Naresh etc. They cover all the courses. Learn Java. If you learn Java, later C# becomes easier.
hi sir give advanced java website
Hello sir ,
I am currently working on Java /J2EE technology ..this website is such a useful for me and I cleared my basic concept through this site .Collection and OOPS fundamentals are described superbly in this site..
Thank you sir.
Hello Sir, Good Evening…
I am Santosh from Bangalore, i have total 8.2 yrs exp in java/j2ee.i have 5 yrs exp in banking domain.i was employee of Triangle Global. i have very well exp in java, jdbc, servlet,jsp, ejb, jms, struts, hibernate, jpa, j2ee design patterns. and i know very well spring but i don’t have real time exp in spring. In Dec 2011, i leave my job because of some family reason… currently i got offer letter from Accenture for Technical Architect but i don’t know responsibility of Technical Architect and for past 6 months i was disturbed and i didn’t work.. so i am afraid..can you tell me what is exact responsibility of Technical Architect.. give me some advice because of i am too depressed..
Architect job is to design the software. For example, a production company appointed your company to develop the complete software involving production, planning, stores, purchase, planning etc. Now where to start and where to end. It is architect job to design. It is very responsible position because when the coding is half the way, the design fails. All the labor is waste. Anyhow, you can join but some days work under an architect.
Sir,
I want to learn JSF ,please suggest institute name offering this course….
ActiveNet in Ammerpet, Hyd.

Have the habit of google search.

Hello Sir,
I was your student at Config in 2008. I want to find out if you are still teaching core JAVA at Config. When my younger brother wanted to learn java, I suggested to go to Config only if you are teaching there and he said you were not there.
Please tell me in which institute are you teaching now so that I can send my brother to your classes.
Thanks & Regards,
Ramya
Yes, I am teaching still at Config. I developed a free web site way2java.com for the programmers liking to learn core java in depth. Refer it.
Thank you so much. It is helping me a lot.
