    import io.netty.channel.socket.SocketChannel;
    import io.netty.channel.socket.nio.NioSocketChannel;
    import io.netty.handler.codec.string.StringEncoder;

    import java.io.IOException;
    import java.net.UnknownHostException;
    import java.util.concurrent.ExecutionException;
    import java.util.concurrent.TimeoutException;

    public class TestNettyTcp {
        private EventLoopGroup group;

        private Channel ch;

        public static void main( String[] args )
            throws UnknownHostException, InterruptedException, IOException,  ExecutionException,  TimeoutException {
