I don't think it would be appropriate to just give you the solution (which would be quite an amount of code), but there are a few subjects you must know in order to implement the solution:
: Read the API and
Tutorial on the subject. You will need it to connect and execute your queries to the Oracle DB (you will need the Oracle JDBC driver)
- Check out the
classes, you will surely need some of them.
Then write some code and if you fail to achieve the answer to your problem we will gladly help you. Regards,

If I may make a suggestion. I ran into a similar problem with an application that we were developing. The solution we chose was to calculate the difference in milliseconds.
The reson we selected this route is if we had a scenario like;
12-31-2002 23:59:59 and 01-01-2003 00:00:01
-- The real time difference is only 2 seconds.
So using the hour approach would have been inadequate in our situation.
