Repeat the previous programming project, but sort the Pet objects by pet weight instead of by name. After displaying the sorted data on the screen, write the number and percentage of pets that are under 5 pounds, the number and percentage of pets that are 5 to 10 pounds, and the number and percentage of pets that are over 10 pounds.

Previous programming project

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.
