How am I to know what effort you've expended? You neither told nor showed.

You don't learn Java in 48 hours, however similar the syntax might be to C/C++. I would suggest that you review your posts with an analytical and unbiased mind. I would also suggest that you still haven't indicated that you aren't looking for some free production.

If you're expecting to learn Java by posting a few things in a C forum, I'm afraid you're going to be disappointed. If you're expecting to get the work done for free, you might very well luck out. Who knows?
