title: Need assistence displaying value from a different private class
body: <p>Okay, first off I am very, very new to java. For this project I need to design a program that takes a product number, an amoutn sold, calculates the total, and then displays it. However, I need to to display when I select option 2, which is a seperate private class, to be honest I don't even know where to begin. Any help would be appreciated.</p>
