The default locale is set via the Regional Settings control panel on Windows or the environment variable LANG on Unix.  To see Stocks for other than the default locale, add the desired locale to the URL as a query string.  For example: http://169.139.223.10/pollock/AJava/Stocks/Stocks.htm?fr_FR

The locale can be a language code only, language_country, or language_country_variant.  The supported locales are currently French ("fr"), Spanish ("es"), and US English ("en_US").

Unknown locales use the nearest match.  The US English locale is the default for completely unknown languages.  See the Java API docs for java.util.ResourceBundle for more details.
