I need some help with, I guess a simple networking related problem I'm having. It will also help me better understand how all this works by knowing what isn't being .close()'ed. I'm sure this is pretty simple, but for me its all very new. This is the client program. I can most likely append the server then, if I can figure this out. Thanks

    public class Server {
    public static void main(String[] args) {
        start();
    }

    static int start = 0;

    public static void start() {
        try {
            ServerSocket serverSocket = new ServerSocket(4567);
            Socket socket = serverSocket.accept();
            //1) Take and echo input (In this case a message)
            BufferedReader bf = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            String message = bf.readLine();
            System.out.println("Message recieved from Client:" + message);
            //2) Response of client message
            PrintWriter printWriter = new PrintWriter(socket.getOutputStream(), true);
            printWriter.println("Server echoing back the message ' " + message + " ' from Client");
        } catch (IOException e) {
            System.out.println("e " + e);
            System.exit(-1);
        }
        start++;

            clearUp();

        if (start < 5) {
            System.out.println("Closing binds and Restarting" + start);

            start();
        }
    }

    public void clearUp(){
        //How would I clear the stuff that is left bound
          so I can restart via start() and avoid the
          java.net.BindException: Address already in use: JVM_Bind ?
    }

}

How would I clear the stuff that is left bound so I can restart via start() and avoid java.net.BindException: Address already in use: JVM_Bind ?
