This chat is Server/Client application, therefore there are two files in this repository: Server.jar and Client.jar
To launch a server, simply type this in your terminal:
$ cd /Path/To/Srerver/File
$ java -jar Server.jar <port>
To connect to a server just type this:
$ cd /Path/To/Client/File
$ java -jar client.jar <ip> <port> <login>
It connects to server with login, that you like to use.
