There's is no difference between Event Handling in Java 1.1 and Java 2.
There is a world of difference between those and Java 1.0.2
The details of those differences are outside of the scope of this Forum. They
are interesting, if you ask me. If you want to be a top-notch Java programmer it helps to know the complete history of the language, from 1995 to today... (IMO).
Then again, I am a purist
