    Why do someone overriding a method and changing its content rather than creating a new method, what is the difference between them. Is it a performance issue or other things? anyone knows the answer plsss help. Thks in advance.

    That's a fundamental part of OOP. You have a class work with Animal, call Growl on the animal, and have the subclass determine what to actually do.
