Storing a file in the user's directory in cross-platform Java

Question

I have a Java application that runs on Mac and Windows, directly off a CD/DVD with no installation. Now, I need to store a file containing per-user data (think favourites etc.) somewhere on the local file system, so that it can be written to.

So, where do you think is a good location for this file? I am thinking something like:

<USER_DOCUMENTS_AND_SETTINGS>/application data/myapp/favourites.db for windows <USER_HOME_DIR>/.myapp/favourites.db for mac/nix

Thoughts? And does anyone know the best way to determine these paths within Java?

Answer 1

System.getProperty("user.home")
