Datagrams are not a reliable network protocol; what do you have planned for in case you drop a packet?
Your queries question, apart from the fact you'll be using JDBC, is really an SQL question. Normally I'd suggest you put it in the SQL forum, but it's really a trivial query. I think all you really need to do is look up how to use SELECT and ORDER for your database; the query itself should be quite trivial. Give it a shot on your own, and if you still have trouble post a question in the SQL forums.
As for the palindrome, work some of it out and let us know if you get stuck. It sounds like you have a decent idea to start out with, although I'm not certain you even need a stack.
BTW, I'm not very good with GUI stuff, so I won't be able to help you out with that stuff. However, if you need help with pretty much anything else I should be able to give you some help. |
