Do the keys() and elements() methods of a Hashtable enumerate things in the same order?

John Zukowski

There is no requirement that the elements are returned in the same order, only that all of them are returned in the Enumeration. Your best bet for getting the element for a key is to loop through the keys() returned and fetch the element for each. Or, if you can use a HashMap instead of a Hashtable, work with the Map.Entry that is returned by the keySet(). This includes both the key and value together, not requiring a separate lookup.
