## 30.20 java.util.ResourceBundle (JDK 1.1)

###

This abstract class allows subclasses to define sets of localized resources which can then be dynamically loaded as needed by internationalized programs. Such resources may include user-visible text and images that appear in an application, and even more complex things such as `Menu` objects.

Use `getBundle()` to load a `ResourceBundle` subclass that is appropriate for the default or the specified locale. Use `getObject()`, `getString()`, and `getStringArray()` to look up a named resource in a bundle. To define a bundle, provide implementations of `handleGetObject()` and `getKeys()`. It is often easier, however, to subclass `ListResourceBundle`, or to provide a property file that is used by `PropertyResourceBundle`. The name of any localized `ResourceBundle` class you define should include the locale language code, and, optionally, the locale country code.

    public abstract class ResourceBundle extends Object {
        // Default Constructor: public ResourceBundle()
        // Protected Instance Variables
                protected ResourceBundle parent;
        // Class Methods
                public static final ResourceBundle getBundle(String baseName) throws MissingResourceException;
                public static final ResourceBundle getBundle(String baseName, Locale locale);
        // Public Instance Methods
                public abstract Enumeration getKeys();
                public final Object getObject(String key) throws MissingResourceException;
                public final String getString(String key) throws MissingResourceException;
                public final String[] getStringArray(String key) throws MissingResourceException;
        // Protected Instance Methods
                protected abstract Object handleGetObject(String key) throws MissingResourceException;
                protected void setParent(ResourceBundle parent);
    }
