String is mutable or immutable?..

Answer / deep

String is neither immutable nor mutable, String is a class Lol.. and string objects are immutable cause you can't change the data which is stored inside in a object..

Let's take a example..
String a = "Dark Knight"; or String a = new String("Dark Knight");

now let's perform operation on String object..
there are some method you can perform on string object so i am gonna perform replace operation..
a.replace("Dark","Blue");

now try to display what's inside String object which is 'a'..
System.out.println(a); // Ans. Dark Knight

System.out.println(a.replace("Dark,"Blue"); // Ans. Blue Knight

but value inside string object is still Dark Knight so to get over this you have to create another object and you have to perform same action again..

String a = "Dark Knight" or String a = new String("Dark Knight");
String b = a.replace("Dark","Knight");

System.out.println(a); // Ans. Dark Knight
System.out.println(b); // Ans. Blue Knight
