java.util.ResourceBundle

New as of JDK 1.1

The PropertyResourceBundle class is a concrete subclass of ResourceBundle that represents a set of resources for a locale. The resources are specified as a set of key/value string pairs in a property file. Internally, a Properties object is used to retrieve the resources from the property file.

When ResourceBundle.getBundle() is called, it attempts to find a resource bundle that most closely matches a particular locale. This can be either a ListResourceBundle subclass or a property file, represented by a PropertyResourceBundle. Once the resource bundle has been retrieved, its contents can be used by the application to present locale-specific information.

PropertyResourceBundle inherits a lot of functionality from ResourceBundle; see the class description of ResourceBundle for more information.
