Advanced Java Programming

One interesting application of computers is to display graphs and bar charts. Write an application that reads five numbers between 1 and 30. For each number thats read, your program should display the same number of adjacent asterisks. For example, if your program reads the number 7, it should display *******. Display the bars of asterisks after you read all five numbers. Also could you please use import javax.swing.JOptionPane; in this application? Thank you.

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, please add 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. Fingers crossed, THANK YOU!!!!! :) :) :)
