Foil 91 Events in the java.awt -- Mouse, Keyboard Interaction - I

From CPS616 Lectures on Java CPS616 Basic Information Track for Computational Science -- Winter-Spring Semester 96. by Geoffrey C. Fox * See also color IMAGE

Events ( distinguish these from Exceptions!) are the way the AWT interacts with the user at mouse or keyboard.
The AWT calls particular event handlers (analogous to exception or interrupt handlers) when user interacts with system in particular ways.
The handling is defined in packages java.awt and java.awt.peer (the machine dependent stuff) with method handleEvent() in class Component(peer)
One could add additional capability here for systems with nifty virtual reality and other user interfaces but we won't cover this here!
public boolean keyDown(Event evt, int key) {} method is called when you press keyboard.
