Event Handling - Listeners

• java.awt.event
  
  
• 11 different sorts of listeners:
  - eg AdjustmentListener for scrollbars;
  - accessed via "interfaces".
  
  
• Interfaces:
  - define methods invoked after events;
  - you OVERRIDE these methods.
  
  
  
• Overriding:
  - supply your own code for method;
  - this then executes after the event.
