Polymorphism - Changing the Shape of Your Program
Polymorphism is the ability of a subclass to define new or share functionality with a superclass. A subclass automatically has possession of public and protected variables and methods in its superclass. These inherited variables and methods can be called directly from an object of the subclass without having to change type. It is possible to redefine variables and methods within a subclass. This creates functionality. In such a case, a variable or method with the same name defined in the subclass overrides the functionality with the same name of the superclass. overload many forms
