                      System

All Implemented Interfaces:

ImageObserver, MenuContainer, Serializable, Accessible, RootPaneContainer

Deprecated. Replaced by Applet.

public class System
extends JApplet

run main in a simulated terminal.

As long as there is no static or explicit reference to System this will spoof standard i/o to and from a text area.

The applet should be a singleton because the i/o connections are static. It is assumed that the AWT components are thread-safe.
