Java oops program like polymorphism and method overriding

Question

Accepted Answer

// Parent class
class Animal {
    // Method that can be overridden
    public void sound() {
        System.out.println("Animal makes a sound");
    }
}

// Child class 1
class Dog extends Animal {
    // Method overriding
    @Override
    public void sound() {
        System.out.println("Dog barks");
    }
}

// Child class 2
class Cat extends Animal {
    // Method overriding
    @Override
    public void sound() {
        System.out.println("Cat meows");
    }
}

public class PolymorphismExample {
    public static void main(String[] args) {
        // Creating objects of different classes
        Animal animal1 = new Animal();
        Animal animal2 = new Dog();
        Animal animal3 = new Cat();
        
        // Calling the method sound
        animal1.sound(); // Output: Animal makes a sound
        animal2.sound(); // Output: Dog barks
        animal3.sound(); // Output: Cat meows
    }
