Understanding Polymorphism in Java | Method Overloading | Core Java Full Course For Beginners

Welcome to Session 12 of our Core Java tutorial series! In this video, we explore Polymorphism in Java—a fundamental concept of object-oriented programming that allows one entity to take multiple forms. Here's what you'll learn:

✔️ What is Polymorphism?
• A single entity exhibiting multiple behaviors.
Examples:
Shape: Rectangle, Square, Circle, Triangle.
Water: Ice, Liquid, Vapor.

✔️ Method Overloading:
• Methods with the same name but different parameters.
Differences in parameters can include:
1️⃣ Number of parameters.
2️⃣ Data types of parameters.
3️⃣ Order of parameters.

✔️ Examples of Method Overloading:
Greeting People: Multiple ways to display greetings.
Payment Methods: Handle different payment types.
Travel Booking: Handle various travel preferences.

✔️ Key Questions Answered:
• Can we pass parameters to the main() method? Yes.
• Can we overload the main() method? Yes.

By the end of this video, you’ll understand how to implement method overloading and leverage polymorphism to build versatile and reusable code in Java.
