Question

Examples: Example 1-Runtime Polymorphism: Lets say we have a class Animal that has a method sound(). Since this is a generic class so we can't give it a implementation like: Roar, Meow, Oink etc. We had to give a generic message public class Animal public void sound System.out.println("Animal is making a sound"); Now lets say we a subclass of Animal class. Horse that extends Animal class. We can provide the implementation to the same method like this: class Horse extends Animal @Override public void sound System.out.println("Neigh"); 3 public static void main(String args[])! Animal obj - owoce obj.sound): 1 Output: Neigh Exercises: Exercise 1. Add a subclass: CreateSUSCISO imal class. Cat. • Create a a sound function with a massage "Meow" inside Cat Class that includes a sound function Call Sound method in Cat class by the reference variable of Animal class

Answer 1

class Animal{
        public void sound() {
                System.out.println("Animal is making a sound");
        }
}

public class Cat extends Animal {
        
        @Override
        public void sound() {
                System.out.println(" Meow");
        }
        public static void main(String[] args) {
                Animal a = new Cat();
                a.sound();
        }
}
