The short answer, is "you can't". A Set is not an ordered Collection.
A longer, and hopefully more useful, answer is that there are a variety of ways that you can get a sorted version of the information that is in a Set.
You could do toArray() on the Set, then Arrays.sort().
You could switch from a Set to a SortedSet such as TreeSet.
You could switch from a Set to a List like ArrayList and use Collections.sort().
There are a variety of reasons for choosing different options. For example, if you need the no-duplicates feature of a Set, then ArrayList is no good. [ November 01, 2007: Message edited by: Peter Chase ]

These are not the droids you are looking for. Perhaps I can interest you in a tiny ad?
