So the mission here is to have all the user input data to display to the display panel. I was able to achieve this, however instead of the info display after I click the display button the info will display after clicking on any of the radio button options. Im hoping someone out there can point me in the right direction so I can get this program to display correctly. There are two classes used in this application.
import java.awt.*;
import java.awt.event.*;
import java.util.Enumeration;
