Please use Code tags, cause if you care about getting the solution, then you should also care about the forum rules.
And one major problem, you have not mentioned the problem, is the program compiling, if not what errors are you getting, if its compiling what is the output you are getting and what do you wish to get ???

Not working can mean a lot of things, especially with relational databases.

Not working as in, you are running a version of Java that may or may not initially support jdbc (versions before 6 I believe) ?

Not working as in, the program wont compile?

Not working as in, the program doesn't work the way you want it to?

So much for telling us "here is the code.. but it is not working.. why?" - please be more elaborate!

Because you haven't provided either any meaningful information, nor shown any effort.

Simply posted a partially complete code and said "do the rest of this for me".

No one is going to give you some sort of magic bullet to solve all the problems in your code, you need to do first what is asked of you, if you expect to find the solution.
