Java chat app using network sockets and Swing for the UI. You can log in anonymously or by using a nickname and chat in private or in a chat room shared by all the active users.
This app was developed as a homework for the "Advanced OOP" course at the University of Bucharest.
- Users can log in with a nickname or anonymously
- Users can open multiple chat windows and chat in private or in the shared chat room
- The nicknames are saved on the client side, so that they can be reused
- The client is build in an MVC fashion and uses Swing as the UI toolkit
- An H2 database is used to store the nicknames on the client side
- The client connects to a socket exposed by the server
- The communication between the client and the server is done using a simple protocol based on the template
"TO: %s, PAYLOAD: %s;", where theTOpart corresponds to a route and thePAYLOADis serialized as JSON. - The network endpoint maps all the known routes to actions that take as an argument the payload
- The server uses a MySql database to keep track of the users and the messages, so that the messages are not lost between restarts.
- The server needs an instance of MySql running on
localhost:3306 - The server handles each client session on a different thread
- Everything is coded keeping in mind the SOLID principles
