Simple chat app that uses WebSockets for communication. This is essentially a fork of MDN example WebSocket chat app.
The main goal of this project was to learn the basics of multithreading in Java, and WebSockets as a bonus.
Comparing to the MDN example chat app, added:
- Multithreading and state shared amongst threads
- Ability to leave chat
- More specific notifications in the chat
- Error handling and username/message text validation
Most of the functionality was added to make thread management more interesting.
To try out the app, first clone the repo. You'll need a jar for Gson library. After you have Gson working, start the server (the entry point is Server.main method). Each client has to be opened in a separate browser tab or window.
If you notice any bugs, feel free to open an issue :)
