• Example: A capsule that contains medicine and only allows access through a small opening.

4 Pillars of OOPs are Abstraction, Encapsulation, Inheritance, and Polymorphism.

• Abstraction: Hiding implementation details and showing only necessary information.

• Encapsulation: Binding data and functions together and restricting access to them.
