/**
 * {@code ListResourceBundle} is an abstract subclass of
 * {@code ResourceBundle} that manages resources for a locale
 * in a convenient and easy to use list. See {@code ResourceBundle} for
 * more information about resource bundles in general.
 *
 * <P>
 * Subclasses must override {@code getContents} and provide an array,
 * where each item in the array is a pair of objects.
 * The first element of each pair is the key, which must be a
 * {@code String}, and the second element is the value associated with
 * that key.
 *
 * <p>
 * The following <a id="sample">example</a> shows two members of a resource
 * bundle family with the base name "MyResources".
 * "MyResources" is the default member of the bundle family, and
 * "MyResources_fr" is the French member.
 * These members are based on {@code ListResourceBundle}
 * (a related <a href="PropertyResourceBundle.html#sample">example</a> shows
 * how you can add a bundle to this family that's based on a properties file).
 * The keys in this example are of the form "s1" etc. The actual
 * keys are entirely up to your choice, so long as they are the same as
 * the keys you use in your program to retrieve the objects from the bundle.
 * Keys are case-sensitive.
