/* MultipleEvents42.java
 *
 * This program illustrates one way to handle multiple events in a single program - by
 * having a different listener for each event source.  Each listeners is an instance
 * of an anonymous inner class declared a the point where the listener is created,
 * whose actionPerformed() method changes to the appropriate color.
 * The GUI consists of a window that can be drawn in one of three colors, and three
 * buttons that can be used to change the color
