Write a program that creates Pet objects from data read from the keyboard. Store these objects into an instance of ArrayList. Then sort the Pet objects into alphabetic order by pet name, and finally display the data in the sorted Pet objects on the screen. The class Pet is given in Chapter 6, Listing 6.1.
