hi,
the question is fairly simple: is there a clean way to get a random item from an enum?

gues not afaik theres:

there is sticking it in an collection and shuflle() it.
http://java.sun.com/j2se/1.5.0/docs/guide/language/enums.html

or you could do something with values() calculate a random integer between 0 and values().length

It's harder to read code than to write it. - it's even harder to write readable code.

You just want a random member of an enum?  try thhis

enum Foo { .......  }

Foo[] fooValues = Foo.values();
return fooValues[(int)(Math.random()*fooValues.length)];
