Polymorphism Examples in Java 🐾

Polymorphism, meaning "many forms," is a core concept in object-oriented programming (OOP). It allows objects of different classes to be treated as objects of a common superclass. Here are key examples:

1. Method Overriding 🔄

When a subclass provides a specific implementation of a method already defined in its superclass.

class Animal {  
    void sound() {  
        System.out.println("Animal makes a sound");  
    }  
}  

class Dog extends Animal {  
    @Override  
    void sound() {  
        System.out.println("Bark!");  
    }  
}

2. Method Overloading 📌

Multiple methods with the same name but different parameters in the same class.

class Calculator {  
    int add(int a, int b) { return a + b; }  
    double add(double a, double b) { return a + b; }  
}  

3. Interface Implementation 🧩

Objects can take multiple forms by implementing interfaces.

interface Drawable {  
    void draw();  
}  

class Circle implements Drawable {  
    public void draw() {  
        System.out.println("Drawing a circle");  
    }  
}
