Java

Pasted from http://codereview.appspot.com/4754047/:

• Opening brace goes on the same line as the declaration start. This
  is Java style, as opposed to C or C++ where it’s customary to have
  the brace on the next line.

• space after if, for, while etc, so ‘if (cond) { …’ rather than
  if(cond).

• don’t use short-form ifs, even if the consequent/alternative are one
  line long. Doing so may introduce subtle bugs in nested conditional
  code.

• ‘else’ clause can be compacted with the surrounding braces.

• No lines beyond 100 columns. That’s about the place where it stops
  being comfortable for reading on a modern hires monitor.

• No ascii-art in parameter formatting. When you need to break lines
  in parameter lists, just use normal indent. Doing otherwise will
  cause formatting to break if any of the params or methods get
  refactored and renamed.
