Comment

An Immutable object cannot be modified or changed in Java. String

is an Immutable class in Java.

Once a String object is created, it cannot be changed. When we

assign the String to a new value, a new object is created.

public class StringImmutableDemo {
   public static void main(String[] args) {
      String st1 = "Tutorials";
      String st2 = "Point";
      System.out.println("The hascode of st1 = " + st1.hashCode());
      System.out.println("The hascode of st2 = " + st2.hashCode());
      st1 = st1 + st2;
      System.out.println("The Hashcode after st1 is changed : "+ st1.hashCode());
   }
}
