String in Java

he String class represents character strings. All string literals in Java programs, such as "abc", are implemented as instances of this class.

Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example:

     String str = "abc";  

sample program.

import java.io.*;

public class stringsample

{

public static void main(String args[])

{

System.out.print("Hello World");

System.out.print("Welcome to my String Java program");

}

}
