The JDK 1.02 event model uses an event inheritance or bubbling approach. In this model,components are required to handle their own events. If they do not handle a particularevent, the event is inherited by (or bubbled up to) the component's container. Thecontainer then either handles the event or it is bubbled up to its container and so on, untilthe highest-level container has been tried..In the event-delegation model, specific objects are designated as event handlers for GUIcomponents. These objects implement event-listener interfaces. The event-delegationmodel is more efficient than the event-inheritance model because it eliminates theprocessing required to support the bubbling of unhandled events.
