Why can I get Environment Variable that isn't defined in the Control Panel

I'm using Java to get "USERDOMAIN" by 

        String domainname = System.getenv("USERDOMAIN");
        System.out.println(domainname);

I can get the domain I want. However, I'm a little confused cause I can't find the "USERDOMAIN" under "System Properties --> Advanced --> Environment Variables". If it's not defined here, where is it defined? How can I know what Environment Variables I can get besides that listed on the Control Panel.

I have tested it on both win7 and win8. Thanks for your help in advance.

On the command line, type set. Per the link, Type SET without parameters to display the current environment variables.
