To know about Java transient, first you must understand Serialization because the roots of transient lies in Serialization or transient is used only with Serialization and in other places it is never used at all. By the by, transient is a keyword of Java used as access modifier (like static, final etc). It is used …
Java Made Simple: What is Java transient variable? Read More »
As much Java knows how to use objects, perhaps no other language knows. You can assign the properties of one object to another in three ways – Shallow copying, Deep copying and Cloning. You can imagine a simple primitive data type as an object with wrapper classes. You can see a system IP address or …
We know earlier in "What is Serialization?", to write an object to a file, the object must be serialized. For this reason, the Student class was serialized in "Java Serialization Example" and then Student objects are written to a file. It is all okay, but if would like to write a string to a file …
After knowing what is serialization, let us know something more. To support serialization, java.io package comes with interface Serializable and two classes ObjectOutputStream and ObjectInputStream. 1. class java.io.ObjectOutputStream Following is the class signature public class ObjectOutputStream extends OutputStream implements ObjectOutput, ObjectStreamConstants The methods of ObjectOutputStream are capable to save the state of primitive data types …
Serialization Introduction Before going into the subject, let us see some code which is very laborious and how Serialization makes it easy. import java.io.*; public class Student { int marks; String name; public static void main(String args[]) throws IOException { Student std1 = new Student(); std1.marks = 50; std1.name = “S N Rao”; DataOutputStream dos …
After knowing what is serialization and the classes available supporting serialization, let us write a program where a Student object is serialized, Student objects are written to a file and later read from the file. In this program, usage of access modifier "transient keyword" is illustrated (observe, the string address variable in the next program). …
