How can I change the indent level for Java code from 4 spaces to 2 spaces?

(add-hook 'java-mode-hook
           (lambda ()
             (set 'c-basic-offset 2)))

                ^^^^^
               (setq c-basic-offset 2)

`set' is very bad style here.

Out of curiosity, can you explain why setq is better then set?  

Thanks in advance,

Because it's the convention to only use set when the SYMBOL isn't known
(lexically) and has to be determined by evaluation.

Because (setq foo bar) == (set 'foo bar) == (set (quote foo) bar),
but setq doesn't require the Lisp reader to allocate 2 cons cells
for (quote foo).

- You can't make `set' lexically scoped.
- You can't (in general) analyse `set' to see if the variable was properly
  declared, etc... so the byte-compiler can't make sanity checks
  or optimizations.
- Basically `set' is in the same category as `eval' which is also
  something to keep the few cases where nothing else works.
