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.

Surprisingly, you can have more than one top-level class in a Java file.    But only one can be public, the others have default protection, and are not accessible from outside the file.
(I've only found this out recently, some months ago, even though I've programming in Java for quite longer)
