Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    Socket socket = new Socket("localhost", 12900);
    System.out.println("Started client  socket at " + socket.getLocalSocketAddress());
    BufferedReader socketReader = new BufferedReader(new InputStreamReader(socket.getInputStream()));
    BufferedWriter socketWriter = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
    BufferedReader consoleReader = new BufferedReader(new InputStreamReader(System.in));

    String promptMsg = "Please enter a  message  (Bye  to quit):";
    String outMsg = null;/*from  w w w  . j a  v a  2 s  .  c  o  m*/

    System.out.print(promptMsg);
    while ((outMsg = consoleReader.readLine()) != null) {
        if (outMsg.equalsIgnoreCase("bye")) {
            break;
        }
        // Add a new line to the message to the server,
        // because the server reads one line at a time.
        socketWriter.write(outMsg);
        socketWriter.write("\n");
        socketWriter.flush();

        // Read and display the message from the server
        String inMsg = socketReader.readLine();
        System.out.println("Server: " + inMsg);
        System.out.println(); // Print a blank line
        System.out.print(promptMsg);
    }
    socket.close();
