I modified eclipse formatter options to do it exactly the way I want : - 80 caracters per line - blank line before the 1st member in classes...
Also, Checkstyle checks more than what the Eclipse formatter does I believe.Their scope are different.
For instance, checkstyle will tell you that your variable name is not correct, or that you should use a keyword in a specific situation. Eclipse, will only put the right tabulation.
I use both.
I have a question though. Checkstyle keeps telling me that my methods should have final arguments. is that something I should really do ? It also bugs me with the order of keywords "final public static" Is that important also ?
