Question

Accepted Answer

OOPs stands for Object-Oriented Programming. It is based on four main pillars: Inheritance, Encapsulation, Abstraction, and Polymorphism.

Inheritance: Allows a class to inherit properties and behavior from another class. Example: class B extends class A.
Encapsulation: Bundling data and methods that operate on the data into a single unit. Example: using private access modifiers to restrict access to certain data.
Abstraction: Hiding the complex implementation details and showing only the necessary features of an object. Example: using abstract classes or interfaces.
Polymorphism: Ability of an object to take on many forms. Example: method overloading and method overriding.
