Please find the updated code below:

TestAnimals.java

package classes9;

class Animal

{

public Animal()

{

System.out.println("A new animal has been created!");

}

public void sleep()

{

System.out.println("An animal sleeps...");

}

public void eat()

{

System.out.println("An animal eats...");

}

}

class Cat extends Animal

{

public Cat()

{

super();

System.out.println("A new cat has been created!");

}

public void sleep()

{

System.out.println("A cat sleeps...");

}

public void purr()

{

System.out.println("A cat purrs...");

}

public void eat()

{

System.out.println("A cat eats...");

}

}

class Dog extends Animal

{

public Dog()

{

super();

System.out.println("A new dog has been created!");

}

public void sleep()

{

System.out.println("A Dog sleeps...");

}

public void bark()

{

System.out.println("A Dog barks...");

}

public void eat()

{

System.out.println("A Dog eats...");

}

}

public class TestAnimals{

public static void main(String args[]){

Cat cat = new Cat();

cat.eat();

cat.sleep();

cat.purr();

System.out.println();

Dog dog = new Dog();

dog.eat();

dog.sleep();

dog.bark();

}

}
