Given the Pets3 program below, write an abstract Animal2 class that contains just one item—an abstract declaration for a speak method. Write Dog2 and Cat2 classes that extend Animal2, so that when you run the Pets3 program and input either a ‘c’ or a ‘d,’ the program prints either “Meow! Meow!” or “Woof! Woof.”

import java.util.Scanner;public class Pets3{public static void main(String[] args){Scanner stdIn = new Scanner(System.in);Animal2 animal;System.out.print("Which type of pet do you prefer?\n" +"Enter c for cats or d for dogs: ");if (stdIn.nextLine().charAt(0) == 'c'){animal = new Cat2();}else{animal = new Dog2();}animal.speak();} // end main} // end Pets3 class
