In javastring objects are immutable. Immutable simply means unmodifiable or unchangeable.

Once string object is created its data or state can't be changed but a new string object is created.

class Test

{  

public static void main(String args[])

{  

 String s="John";  

 s.concat(" Fernandis");

 System.out.println(s);

 }  

}
