        // to a Parent object, then Parent's

        // show is called

        Parent obj1 = new Parent();

        obj1.show();

  

        // If a Parent type reference refers

        // to a Child object Child's show()

Overriding is done so that a child class can give its own implementation to a method which is already provided by the parent class.
