The i18n Cookbook - recipies for a global society

Problem:

You want to retrieve all ISO639 language codes or ISO3166 region codes.

Solution:

You can retrieve both ISO 639 language codes and ISO 3166 country codes by calling static methods on the Locale class.

To retrieve the ISO 639 language codes:

String[] locales = Locale.getISOLanguages();

for(int x = 0; x < locales.length; x++){

  System.out.println(locales[x]);

}

To retrieve the ISO 3166 country codes:

String[] locales = Locale.getISOCountries();

for(int x = 0; x < locales.length; x++){

  System.out.println(locales[x]);

}
