Multicasting

• Since our listener classes are objects, we can have one listener object and add it to multiple components.
• Example: a Close button and the 'X' icon on the frame might share the same window closing listener.
• We can also register multiple listeners on the same component.
• We might have certain buttons or text fields on a data form that automatically save the contents of that form to a database when an event occurs.  These buttons might have their own listener to perform validation or other actions, and share a save listener that saves the state of the form.
• Having multiple listeners is called Mulitcasting.
