1) In the Animal class,add an input String parameter to the constructor called type, which we will use to identify the type of animal. Add the appropriate private member variable to copy the input parameters value into and a public accessor method called getType().

2.) In each of the Dog, Cat, Bird, Fish, and Fox classes, add the corresponding type of the animal to the call to the super class constructor. To be super clear by type, I mean Dog for the Dog class, etc...

3.) Back in the Animal class, make it an abstract class and make each of the following methods abstract: numberOfLegs(), numberOfWings(), and breatheUnderwater().

4.) In the Tester class:

a. Remove all the code in the main method aside from the creation of the five animal objects.

b. Create and initialize a variable of type ArrayList.

c. Add each of the five animals into the ArrayList.

d. Use the enhanced for loop syntax to iterate over the ArrayList and call the PrintDetails method for each animal in the ArrayList.

e. Create a method with the following signature:

public static void PrintDetails( Animal a )

That method should use the public methods available on the Animal class to determine if the animal it was passed has legs, wings or gills and in each case call numberOfLegs(), numberOfWings(), or breatheUnderwater() as appropriate. Also call getSoundMade(). You will need to use the getType()method we added in order to produce the sample output below exactly.
