## 30.11 java.util.ListResourceBundle (JDK 1.1)

###

This abstract class provides a simple way to define a `ResourceBundle`. You may find it easier to subclass `ListResourceBundle` than to subclass `ResourceBundle` directly.

`ListResourceBundle` provides implementations for the abstract `handleGetObject()` and `getKeys()` methods defined by `ResourceBundle`, and it adds its own abstract `getContents()` method that your subclasses must override. `getContents()` returns an `Object[][]`--an array of arrays of objects. This array can have any number of elements. Each element of this array must itself be an array with two elements: the first element of each subarray should be a `String` that specifies the name of a resource, and the corresponding second element should be the value of that resource--this value can be an `Object` of any desired type.

See also `ResourceBundle` and `PropertyResourceBundle`.

    public abstract class ListResourceBundle extends ResourceBundle {
        // Default Constructor: public ListResourceBundle()
        // Public Instance Methods
                public Enumeration getKeys();  // Defines ResourceBundle
                public final Object handleGetObject(String key);  // Defines ResourceBundle
        // Protected Instance Methods
                protected abstract Object[][] getContents();
    }
