What are the important pillars of OOPs ? Explain it.

Encapsulation: Bundling data and methods that operate on the data within a class, hiding the internal state of objects. Abstraction: Hiding complex implementation details and showing only the essential features of an object. Inheritance: Allowing a class to inherit properties and methods from another class, promoting code reuse. Polymorphism: Enabling objects to be treated as instances of their parent class, allowing a single function to behave differently based on the object type.
