Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
Example: Inheritance in programming languages like Java allows a parent class to have multiple child classes with different implementations of the same method.
Example: A shape class with different subclasses like ...
