Polymorphism in Java

📌 What is Polymorphism? Polymorphism means “many forms.” In Java, polymorphism allows the same method name to behave differently based on the situation. 🎯 Types of Polymorphism in Java Java supports two types: Compile-time Polymorphism (Method Overloading) Runtime Polymorphism (Method Overriding) 1️⃣ Compile-Time Polymorphism (Method Overloading) Same method name Different parameters Decision made at compile time Example: class Calculator { int add(int a, int b) { return a + b; } double add(double a, double b) { return a + b; } } public class Main { public static void main(String[] args) { Calculator c = new Calculator(); System.out.println(c.add(5, 3)); System.out.println(c.add(2.5, 3.5)); } } 2️⃣ Runtime Polymorphism (Method Overriding) Same method name Same parameters Different implementation in child class Decision happens at runtime. Example: class Animal { void sound() { System.out.println("Animal makes sound"); } } class Dog extends Animal { void sound() { System.out.println("Do
