Jeff,
Yeah, we do something similar in our applications. The easiest way to sort
those items is to make a TreeMap with a Comparator that sorts your objects
with the proper key, and then call putAll() on the TreeMap passing your
existing HashMap as a parameter.
Or you could just blow off the HashMap altogether and just use the TreeMap
from the beginning... depending on the number of objects we're talking
about, the performance wouldn't be much different (AFAIK).
