🟢 Java Abstract Shapes – OOP Demonstration

Today I studied some important Object-Oriented Programming (OOP) concepts in Java and implemented a simple task to practice them.

This project demonstrates Abstraction, Inheritance, and Polymorphism using an abstract class. 📚 What I Learned Today

✅ Abstract Classes

✅ Method Overriding

✅ Inheritance

✅ Runtime Polymorphism

✅ Clean OOP Structure

After understanding these concepts, I performed a small task to calculate the area of different shapes using abstraction.

📂 Project Description

An abstract class shape contains an abstract method:

abstract double area();

Two classes extend it:

Circle → Calculates area using formula: π × r²

rectAngle → Calculates area using formula: length × width

In the main method, polymorphism is demonstrated by creating references of type shape.

This small project helped me understand how abstraction works in real coding practice 💡
