Answer / sharief
Yes,String is immutable.The simple meaning of immutable is
unmodifiable or unchangeable.once String object has been
created,its value can not be changed.
The Reason is java uses concept of String literal.Suppose
there are 5 reference variables,all referring to an object
called "Ronaldo".If one reference variable changes the value
of the object,it will be affected to all the reference
variables.That is why String objects are immutable in java.

Answer / java
String s = "PROJECT";
String s2 = s.toLowerCase();
System.out.println(s.equals("PROJECT")); // Prints true
System.out.println(s.equals(s2)); // Prints false
In comparison, consider what would happen if Strings were mutable.
MutableString ms = "PROJECT";
MutableString ms2 = ms.toLowerCase();
System.out.println(ms.equals("PROJECT")); // Prints false
System.out.println(ms.equals(ms2)); // Prints true
