http://www.loc.gov/standards/iso639-2/englangn.html The country argument is a valid ISO Country Code. These codes are the upper-case, two-letter codes as defined by ISO-3166. You can find a full list of these codes at a number of sites, such as:

The variant argument is a vendor or browser-specific code. For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX. Where there are two variants, separate them with an underscore, and put the most important one first. For example, a Traditional Spanish collation might construct a locale with parameters for language, country and variant as: "es", "ES", "Traditional_WIN".
Because a Locale object is just an identifier for a region, no validity check is performed when you construct a Locale. If you want to see whether particular resources are available for the Locale you construct, you must query those resources. For example, ask the NumberFormat for the locales it supports using its getAvailableLocales method.
Note: When you ask for a resource for a particular locale, you get back the best available match, not necessarily precisely what you asked for. For more information, look at {@link ResourceBundle}.
The Locale class provides a number of convenient constants that you can use to create Locale objects for commonly used locales. For example, the following creates a Locale object for the United States:
Locale.US
Once you've created a Locale you can query it for information about itself. Use getCountry to get the ISO Country Code and getLanguage to get the ISO Language Code. You can use getDisplayCountry to get the name of the country suitable for displaying to the user. Similarly, you can use getDisplayLanguage to get the name of the language suitable for displaying to the user. Interestingly, the getDisplayXXX methods are themselves locale-sensitive and have two versions: one that uses the default locale and one that uses the locale specified as an argument.
The Java Platform provides a number of classes that perform locale-sensitive operations. For example, the NumberFormat class formats numbers, currency, or percentages in a locale-sensitive manner. Classes such as NumberFormat have a number of convenience methods for creating a default object of that type. For example, the NumberFormat class provides these three convenience methods for creating a default NumberFormat object:
These methods have two variants; one with an explicit locale and one without; the latter using the default locale.NumberFormat.getInstance() NumberFormat.getCurrencyInstance() NumberFormat.getPercentInstance()
ANumberFormat.getInstance(myLocale) NumberFormat.getCurrencyInstance(myLocale) NumberFormat.getPercentInstance(myLocale)
Locale is the mechanism for identifying the kind of object (NumberFormat) that you would like to get. The locale is just a mechanism for identifying objects, not a container for the objects themselves.

A Locale object defines methods to set and get its high-resolution coordinates, and methods to add, remove, and enumerate the branch graphs.
