/* MenuOptionsDemo.java

 * This program illustrates both options for creating menus in a single program:
 * a "native awt" menu, and a "swing" menu.  ONE WOULD NOT ORDINARILY DO THIS IN
 * A SINGLE APPLICATION - IT IS BEING DONE HERE ONLY TO ILLUSTRATE THE DIFFERENCE
 * BETWEEN THE TWO APPROACHES TO MENUING
