Polymorphism in Java | Compile-time and Runtime Explained with Examples | DAY - 13
Welcome back to Day 13 of Java in 30 Days by Quipoin!
In today’s lesson, we are diving into one of the four pillars of Object-Oriented Programming (OOP) — Polymorphism.
Polymorphism simply means “one thing, many forms” and in Java, it comes in two types:
Compile-Time Polymorphism → Method Overloading
Run-Time Polymorphism → Method Overriding
In this video, you will learn:
What Polymorphism means in Java
The difference between Overloading (compile-time) and Overriding (runtime)
Code examples with Shape, Circle, Rectangle, and Calculator classes
Why Polymorphism makes Java flexible & powerful
