Implementation of a Chat Program using TCP Sockets

The goal of this project was to implement a chat program using TCP sockets. The program should provide multiple chat rooms, and allow users in different chat rooms to send private messages to each other.

When a client connects to the server, the server creates a User object that holds the socket. The string input by the user on the client-side is encoded into an appropriate message and sent to the server, where the Processor performs the corresponding action based on the received message. The Processor manipulates instances of User and Room while performing the action. For example, if the action is "send", the content of the message is sent to other User objects in the same Room. The client that receives the message interprets it and displays it on the terminal.
