Resource bundle used to contain locale-specific objects. When your program needs a locale-specific resource, a String for example, your program can load it from the resource bundle that is appropriate for the current user\'s locale. This allows you to write programs that can: * be easily localized, or translated, into different languages. * handle multiple locales at once. * be easily modified later to support even more locales. The Java ResourceBundle class eases the process of separating localized resources from an application\'s source code, but you may want to extend the ResourceBundle class to better fit your needs.
