Is there any java libraries that is similar to unix's command file?

ie:

$ file somepicture.png
somepicture.png PNG image, 805 x 292, 8-bit/color RGB, non-interlaced

The file command is such a nice tool. I need something that can tell me if the file is really what I want it to be. (ie a picture, document etc)

I know I can run the command file, but I am looking for a java library, not running the actual unix command.
