public static String[] getISOLanguages ()

Returns a list of all 2-letter language codes defined in ISO 639. Can be used to create Locales.

Note:

• ISO 639 is not a stable standard— some languages' codes have changed. The list this function returns includes both the new and the old codes for the languages whose codes have changed.
• The Locale class also supports language codes up to 8 characters in length. Therefore, the list returned by this method does not contain ALL valid codes that can be used to create Locales.

Returns:  Am array of ISO 639 two-letter language codes.
