多个线程写入一台服务器

Question

I have a problem. I want to create a network connection so that I can make a multiplayer game. I know and understand sockets. My problem is that if I press two keys on the keyboard at the same time it writes to the socket at the same time which causes an error. What I then did was create multiple sockets for one client to writ to and only writes to a socket that isn't busy. By for some reason seems to overload it or something. Any ideas for simultaneously sending messages to server and vice versa.

Answer 1

Is your code doing like this in server?

    while (true) {
        try {
            socket = serverSocket.accept();
        } catch (IOException e) {
            System.out.println("I/O error: " + e);
        }
        // new threa for a client
        new MyThread(socket).start();
    }

then, inside MyThread#run

    inp = socket.getInputStream();
    brinp = new BufferedReader(new InputStreamReader(inp));
    out = new DataOutputStream(socket.getOutputStream());
    line = brinp.readLine(); // read the data.
    out.writeBytes(line + "\n\r"); //write back to client
    out.flush(); // flush socket

Java NIO would faster and efficient. Please refer open source netty servers as well.
