Usage

From source file:Test.java

public static void main(String[] args) throws Exception {

    AsynchronousSocketChannel client = AsynchronousSocketChannel.open();
    InetSocketAddress address = new InetSocketAddress("localhost", 5000);

    Future<Void> future = client.connect(address);
    System.out.println("Client: Waiting for the connection to complete");
    future.get();// ww w . j a  v  a2 s.  c  o m

    String message = "";
    while (!message.equals("quit")) {
        System.out.print("Enter a message: ");
        Scanner scanner = new Scanner(System.in);
        message = scanner.nextLine();
        System.out.println("Client: Sending ...");
        ByteBuffer buffer = ByteBuffer.wrap(message.getBytes());
        System.out.println("Client: Message sent: " + new String(buffer.array()));
        client.write(buffer);
    }
}
