The internationalized program is flexible; it allows the end user to specify a language and a country on the command line. In the following example the language code is fr (French) and the country code is FR (France), so the program displays the messages in French:

% java I18NSample fr FR
Bonjour.
Comment allez-vous?
Au revoir.

In the next example the language code is en (English) and the country code is US (United States) so the program displays the messages in English:

% java I18NSample en US
Hello.
How are you?
Goodbye.
