Java server testing material. Connection. String and object sending/receiving. Threading.

These are all my server testing material so far. Sadly, server will need to be redesigned. Lots of the code is on oracle. Only the most recent server is mostly original. Still has connection and pacing issues. Data classes need to be restructured. Thread handling needs to be optimized. Thread passing may also need to be redone. Data persistence needs to be implemented. Server is currently only receiving and not sending data out in response. However, general idea of the server is there.
