This project is a comprehensive Java-based implementation that demonstrates all four core Object-Oriented Programming (OOP) principles — Encapsulation, Inheritance, Polymorphism, and Abstraction — through real-world inspired examples and clean modular structure.
This project demonstrates all four core Object-Oriented Programming principles in Java through clean, real-world-inspired examples:
-
✅ Encapsulation
-
✅ Inheritance
-
✅ Polymorphism (Compile-time & Runtime)
-
✅ Abstraction (Abstract Classes & Interfaces)
| Concept | Topics Demonstrated |
|---|---|
| Encapsulation | Private fields, getter/setter methods, controlled access |
| Inheritance | Base/derived classes, constructor chaining, method reuse |
| Polymorphism | Method overriding, runtime resolution, superclass references |
| Abstraction | Interfaces, abstract classes, loose coupling, modular design |
- Compile all Java files
'''bash javac src/OOPS///*.java'''
🧠 What You’ll Learn How to use interfaces and abstract classes to create flexible designs How to override methods and achieve runtime polymorphism How access modifiers work and why encapsulation matters How composition is more powerful than inheritance in real-world systems
💻 Requirements Java 8 or above
Terminal / IDE (VS Code, IntelliJ)
