    Default From C# to Java

    I want to do theese lines in java...
      protected Socket _sck;
            protected string _host;
            protected UInt16 _port;
     
     
            public void Connect(string RemoteHostIP, UInt16 RemotePort)
            {
                if (this._sck != null)
                {
                    this._sck.Close();
                    this._sck = null;
                }
     
                this._sck = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
                this._host = RemoteHostIP;
                this._port = RemotePort;
                try
                {
                    this._sck.BeginConnect(new IPEndPoint(IPAddress.Parse(this._host), this._port), new AsyncCallback(this.onSocketConnected), this._sck);
     
                    // Raise the event.
                    this.OnConnectionAttempt(new SocketConnectEventArgs(this._host, this._port));
                }
                catch (SocketException se)
