GNU Emacs: Avoid huge indentations in Java

Ever going crazy of default indenting of Java sources by Emacs? What about code like this?

Much better, right? Here I use two things:

1. No tabs — see No tabs article.
2. I use custom c-mode-hook.

The custom hook should reside in your “.emacs” file like that:

(defun my-c-mode-hook ()
  (c-set-offset 'substatement-open 2)
  (setq c-basic-offset 2))

It is “plugged” to do its work when pressing TAB in Emacs, like that:

(add-hook 'c-mode-common-hook 'my-c-mode-hook)
