Polymorphism in Java 📍 Polymorphism allows a single interface to be used for different types of actions. 📍 It is of two types: Method Overloading (Compile-time Polymorphism) Method Overriding (Runtime Polymorphism) Method Overloading (Same method name, different parameters) class MathOperations { int add(int a, int b) { return a + b; } double add(double a, double b) { return a + b; } } Method Overriding (Same method in parent and child class) class Animal { void makeSound() { System.out.println("Animal makes a sound"); } } class Dog extends Animal { void makeSound() { System.out.println("Dog barks"); } } 🔗 More Java Resources: https://whatsapp.com/channel/0029VamdH5mHAdNMHMSBwg1s
