Chapter 10, Problem 8PP

Write a program that reads records of type Pet from a file created by the program described in the previous programming project and displays the following information on the screen: the name and weight of the heaviest pet, the name and weight of the lightest pet, the name and age of the youngest pet, and the name and age of the oldest pet.

Revise the class Pet, as shown in Listing 6.1 of Chapter 6, so that it is serializable, Write a program that allows you to write and read objects of type Pet to a file. The program should ask the user whether to write to a file or read from a file. In either case, the program next asks for the file name. A user who has asked to write to a file can enter as many records as desired. A user who has asked to read from a file is shown all of the records in the file. Be sure that the records do not scroll by so quickly that the user cannot read them (Hint: Think of a way to pause the program after a certain number of lines are displayed.)
