How do I get the value of Windows' %APPDATA% location variable in Java?

I'm trying to make my program save its state in the location set by %APPDATA% when the user is using Windows. However, System.getProperty("temp.dir"); does not return that. How do I get the value of the %APPDATA% variable in Windows, for the purpose of state saving?

Solution

  • Use System.getenv()

    System.getenv("APPDATA")

    But I think 

    System.getProperty("user.home")

    should be preferred even though it's not exactly the same thing because it is more portable.
