CSE 331 Software Design & Implementation. The basic event handling model is for every event to be tied to an event handler – some program text that is coded to correctly respond to the event. This event handler is called – by the control program, i.e. the virtual machine, operating system or whatever – whenever the event occurs. The Java model implements this by providing various listener interfaces in the java.awt.event package The basic event handling model is for every event to be tied to an event handler – some program text that is coded to correctly respond to the event.
