What's the difference between user.region, user.language, user.country and user.variant?

I've recently had a problem with Java locales in my system, and I was trying to run a project with this configuration:

-Duser.language=pt_BR
-Duser.country=BR

After googling, I found this site which had me changing my configuration to:

-Duser.language=pt
-Duser.region=BR
-Duser.country=BR

And the problem was gone. Additionaly I've found pages like this talking about using another property called user.variant.

I'm not after LC_* properties, I'm just trying to find out what's the difference between these four properties?

user.language
user.region
user.country
user.variant

Thanks

  • Please take a look at the javadoc of Locale http://docs.oracle.com/javase/7/docs/api/java/util/Locale.html

    It describes language, variant, and so on.
