Automatically pretty format large number of Java source files

I have many Java files from a project which have not been formatted properly. Also due to enforcement of a common style many people have introduced their own coding style. I want to bring all this code to one consistent format. Are there any auto-formatters available which I can run as script on all the files. I would like to rethink and fine tune following options:

  1. Number of spaces used for indentation.

  2. Spaces around operators like + - * / etc.

  3. Separation between parentheses.

  4. etc.

I was looking at Netbeans auto format and looked cool. Moreover the parameters can be set from the option dialog. However I am not able to completely grasp how to use the API

Well I don't know if you use eclipse, but to do spacing and parenthasis you just press ctrl + shift + f and to do auto indentation is ctrl + i

You can use the Eclipse JavaCodeFormatter from the command line:

The following example runs the formatting of code specified by the configuration file D:/formatter.prefs on the files Java belonging (directly or indirectly) to the directory D:/tmp/src :

eclipse -application org.eclipse.jdt.core.JavaCodeFormatter -config D:/formatter.prefs D:/tmp/src

Try JIndent. Or here're a bunch of open source code formatters for Java, some of them can be run as standalone products, others as plugins inside an IDE (Eclipse, NetBeans).

Why use the API? Bring it in as a NetBeans project. Same with Eclipse or IntelliJ; they can all format all source files in a project.

For standalone, try Jalopy. It can also be set up to run as part of a build, as a commit hook, etc.
