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 allows a child class to override a method from its parent class, exhibiting polymorp...
Encapsulation is the concept of bundling data and methods that operate on the data into a single unit.
