Prerequisites:
You need to have a mysql database with 
Database Name :"cs3002_db"
UserName:"cs3002_user"
Password:"cs3002_password"

Note: No need to have table inside it.. My program automatically creates a 
table (with name cs3002_table). This table is used to store the chat logs and this 
table is created at server side.

How to Run?
1. First run the server program which asks to enter the listening port.

2. If it could bind and listen succesfully then you will enter into chat room, else
   you will get a dialog box with appropriate message.

3. Once the server is started, now you can start running client program on various systems

4. The client program first asks the user to enter the Server IP address, Port and Nick Name (like DC++).
   If the connection is succesfully established. you will enter into the chat room else appropriate error message
   is printed.

NOTE: you cannot login into chat room with nick which is already used by other users.
