ListResourceBundle public abstract class ListResourceBundle extends ResourceBundle ListResourceBundle is a abstract subclass of ResourceBundle that manages resources for a locale in a convenient and easy to use list. See ResourceBundle for more information about resource bundles in general. Subclasses must override getContents and provide an array, where each item in the array is a pair of objects. The first element of each pair is a String key, and the second is the value associated with that key. 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.
