event handling

[stmfc]

hi,
for an event handling mechanism,
we need an event object. (the object where the event actually occur)
and we need an event handler,
and we need a registration of the event handler to the event object(generato r)

in java, we can create a generator class by extending EventObject class.
we can create an event handler class by implementing EventListener interface.

for registration we can provide some registration method (e.g addMyListener )
in our generator class.

my 1st question: can this registration method be like any other method, or is there any restriction on it, or does it have any special behaviour?

my 2nd question: did i figure out event handling issue correctly, or is there any missing/incorrect points?

thanks in advance...

I think you've just about got it.
The addMyListener method must generally accept an EventListener argument.
