How to save files in temp directory for any platform?

Question

I have a Grails application in which I generate PDF/Excel files in a folder.

My problem is, everytime I need to change the directory path through code when I test or run the code on different machines like Windows, Linux, Mac.

So what is the generic path, which will be applicable for any/all platforms as the default temp directory, so that I won't need to manually set path for the directory while running code on different machines/platforms.

Thanks for editing, will reply you after checking your answer. — VVB, Feb 24 '15 at 06:53

The temp directory is available via

String tempDir = System.getProperty('java.io.tmpdir')

To create temp files in the default location for the OS you can use File.createTempFile(prefix,suffix)
