import java.nio.channels.AsynchronousSocketChannel;

import java.util.concurrent.ExecutionException;
import java.util.concurrent.Future;

public class Main {
  
    public static void main(String[] args) {
        try {/*w w  w .j av a  2  s. co  m*/
            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();

            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);
            }

        } catch (IOException | InterruptedException | ExecutionException ex) {
