Java Enums can have behavior?

I'm not quite sure where the title of the question fits in with the rest of it. Yes, Java enums have behaviour. They can have state too, although it should really, really be immutable state. (The idea of a mutable enum value is pretty scary IMO.)

An enum in Java is a fixed set of objects, basically. The benefit is that you know that if you have a reference of that type, it's always either null or one of the well-known set.

Personally I really love Java enums and wish C# had them too - they're much more object-oriented than C#'s enums which are basically "named numbers". There are a few "gotchas" in terms of initialization order, but they're generally fab.
