        The 2nd method you're not instantiating class A, you're instantiating class B :confused:

          You'll get the same output in both cases because, even though you are using class A in the 1st method, you are instantiating an instance of class B (because B inherits from A). What you can't do here, is access methods of B that aren't in A.

          Deja View - the feeling that you've seen this post before.

              if you do like this: A e = new A(); e.get(); B c = new B(); c.get(); you will have Hello and Fine too..

                yes it's correct but if we have A e = new B(); //Upcasting e.get(); we will have "Fine"

                    The question can not be answered, as it's incorrect. Neither of the two methods creates an instance of the A class.

                    Despite everything, the person most likely to be fooling you next is yourself.
