1)here's the Animal class:

public abstract class Animal {public String sound;public abstract void setSound(String sound);public abstract String getSound();}

2) Animaldriver :

public class AnimalDriver {public static void main(String[] args) {Dog dog = new Dog("woof");Cat cat = new Cat("meow");Pig pig = new Pig("oink");System.out.println(dog);System.out.println(cat);System.out.println(pig);}}

Given the parent abstract class Animal a.create child classes Dog, Cat and Pig that implement the methods defined in the abstract class. In addition, create a constructor that takes a string parameter that represents the sound the animal makes and a toString method to provide a string representation of the object in each of the child classes. Your program should run with this diver without modification
