Java class Character static methods explained in simple terms with programs, screenshots
Introduction The java.lang.Character class includes many useful static methods with which text (or characters) can be manipulated. The other text manipulating classes are String, StringBuffer, StringTokenizer and StringBuilder. The Character class is a wrapper class for char data type. That is, a Character object represents char as an object; it gives an object form to …
Java Character API comes with many methods to test whether a character is a digit or letter etc. This type of testing is useful in situations like constraints on passwords, employee id etc. To test for letter, the character class comes with isLetter(char) method. Following is the method signature as defined in java.lang.Character class. public …

Java Character API comes with many methods to test whether a character is a digit or letter or defined in Unicode etc. This type of testing is useful in situations when a Java program can accept a character or not. Following is the method signature as defined in java.lang.Character class. public static boolean isDefined(char ch): …
Java Character API comes with many methods to test whether a character is a digit or letter or defined in Unicode or can suit to be a part of Java identifier etc. This type of testing is useful in situations when a Java program can accept a character or not. Following is the method signature …
Many methods exist in java.lang.Character class used for different purposes. Some methods are useful for checking the character is a digit or letter or is a uppercase letter or lowercase etc. At the sametime, some methods can modify the case of the letters from uppercase to lowercase or vice versa. Few more methods exist whether …

Java is a simple language to practice and develop more code in less time. All this is due to predefined API methods designers add in each version. Good examples are classes like String, Character, GregorianCalendar and LinkedList etc. They are designed as classes and methods are given to manipulate them. For example, addFirst() and addLast() …
Java Character API comes with many methods to convert a character’s type to another type. toUpperCase(char ch) converts lowercase ch letter to uppercase. After conversion, you can check the character is really converted or not with isUpperCase() method. If the character is already an uppercase one, it is returned as it is by the method. …

Java is an object-oriented language where each real life entity can be referred as an object. Towards this goal, Java comes with java.lang.Integer class to represent primitive data type int as an object, java.net.URL class to represent a simple system address like 127.0.0.1 as an object, java.io.File class to give a hard disk file an …
