ZOMG.

You think *anyone* would hire you with something they couldn't even read?

What's with all the fully qualified Class names?

Why are "fizz", "buzz" etc. not static constants and in UPPER CASE?

Did you know that Java includes '}' and that it's very dangerous to not 
surround any if/else clause without them?

And, hey, did you *deliberately* try to format the code in as random a 
way as possible?

Oh wait, I know there have been "most obfuscated code" competitions for 
years, but, sorry, there is at least one "sensible" variable name in 
there (the 'i' in the "for loop").
