What is OOPS?

OOPS - Object-Oriented Programming System is the programming technique to write programs based on real-world objects. The states and behaviors of an object are represented as member variables and methods. 

In OOPS programming programs are organized around objects and data rather than actions and logic.

List of basic and advance OOPS concepts in Java:

1. Object
2. Class
3. Abstraction
4. Encapsulation
5. Inheritance
6. Polymorphism
7. Composition
8. Aggregation
9. Association
10. Cohesion
11. Coupling
12. Delegation
