Java requires you to use classes for anything that has structure or 
anything that can do anything. You can't have two top-level classes in 
one file, though; you need another class to act as a namespace for them.

And using inner classes for events is ugly. I implemented an event 
broker in Java, but I couldn't stand using it because I had to use inner 
classes to get anything done.
