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.
