1. First, create an interface named Pet in a file called Pet.java. This interface shoul have three methods: getName().getType(), and getSound(), all of which return String and should not take anything as arguments. 2. Second, rewrite the Cat class so that it implements the Pet interface. 3. Third, create another class (of your choice) that implements the Pet interface. Make one of the methods interesting in some way (i.e. instead of randomly choosing between two sounds... choose between 3 sounds, or maybe change th name randomly. Whatever strikes your fancy.) 4. Then, modify Main so that you have an ArrayList of Pets. a. If you don't remember how to create an ArrayList... this code will do it: ArrayList pets. = new ArrayList (); pets.add(new Cat ("Bootes")); b. Place in there a mix of Cat and "other" (whatever class you made in step Because we declare the ArrayList to be of type Pet, we can fully leverage polymorphism that is available with the interface. c. Use a for loop to iterate through this array and generate some output to show that you have several Pets of different types. Sample output: This one is a Cat. amed Bootes
