ChatRoom

This is a Chat Server written in Java. It alows users to communicate with one another by connecting to the server and interacting with it in accordance to an application protocol.
Through this protocol, the server allows clients to engage in group chats in chat rooms and send private messages to one another.
The Server uses Socket programming to handle client communication and multi threading to handle concurrent client connections.
