Advanced Java Programming (UPDATED)

An online retailer sells five products whose retail prices are as follows: Product 1, $2.98; product 2, $4.50; product 3, $9.98; product 4, $4.49 and product 5, $6.87. Write an application that reads a series of pairs of numbers as follows:

a) product number

b) quantity sold

Your program should use a switch statement to determine the retail price for each product. It should calculate and display the total retail value of all products sold. Use a sentinel-controlled loop to determine when the program should stop looping and display the final results.

IMPORTANT NOTE!!: This program must use at least 2 classes, getters/setters, etc and other object-oriented design (OOD) concepts as I'm in a more advanced Java class. Also, I need detailed, but brief comments to most, if not all of the code to explain what is being used in the code and what is does so I have a better understanding of the code. Finally, use import javax.swing.JOptionPane; in this application as required for this advanced Java programming class. Fingers crossed, THANK YOU!!!!! :) :) :)
