Which is why it's a bad idea to write code such as this, especially
without any comments.  A code review should reject it (and would on the
projects I have managed).

You can obfuscate your code in almost any language (including Java).
Some make it easier than others.  But that does not mean it's a good
idea.  Unless there is an overwhelming reason otherwise, code should
always be clear and easy to understand - even if it does take a few more
lines to make it so.
