I have a sorting issue with a Hashmap. My constraint is that
I MUST use the Hashmap and work with existing code. I do a
database query and place the results in a Hashmap. When I
iterate thru the Hashmap, it loses the original alphabetical
sorting done by the database. So, my problem is that I must
sort the results coming out of the Hashmap which is then
placed into another class.
