OOPs pillars are the four fundamental concepts of Object-Oriented Programming.
Abstraction: hiding unnecessary details while showing only essential information
Encapsulation: binding data and functions together to protect data from outside interference
Inheritance: creating new classes from existing ones, inheriting properties and methods
Polymorphism: ability of objects to take on many forms or have multiple behaviors
Polymorphism is the ability of an object to take on many forms.
Polymorphism allows objects of different classes to be treated as if they are of the same class.
It can be achieved through method overloading or method overriding.
Example: A shape class can have multiple subclasses like circle, square, etc. and all can be treated as shapes.
Polymorphism helps in achieving loose coupling and flexibility in code design.
