Hi, can you give us a tutorial on how to create a simple chat application using Java socket.
I have read your How to build a server in Java. It was amazing but I wanted to know how can two clients communicate to each other through the server. It would be really helpful if you could help me with this.
Note: I am a beginner and it will be helpful if you can help me on this one.
Here is an example of how to extend a very simple client-server demo program into a fully functioning (but simple) Chat Client/Server package. There are five stages involved:
Step 1: A simple server that will accept a single client connection and display everything the client says on the screen. If the client user types ".bye", the client and the server will both quit.
Step 2: A server as before, but this time it will remain 'open' for additional connection once a client has quit. The server can handle at most one connection at a time.
Step 3: A server as before, but this time it can handle multiple clients simultaneously. The output from all connected clients will appear on the server's screen.
Step 4: A server as before, but this time it sends all text received from any of the connected clients to all clients. This means that the server has to receive and send, and the client has to send as well as receive
Step 5: Wrapping the client from step 4 into a very simple GUI interface but not changing the functionality of either server or client. The client is implemented as an Applet, but a Frame would have worked just as well (for a stand-alone program).
