public class Display
extends javax.swing.JFrame

Display Panel class to implement a simple ``Input'' and ``Output'' panel for elementary Java teaching allowing the novice programmer to concentrate on the basic language syntax while still having access to reasonable window style interface. Orginal concept from Java Gently for Scientists and Engineers. AWT version by Swing version
