HTTP Connection with Sockets

Question

Why does the response come back as nothing assume req="GET HTTP/1.0" and url="http://www.google.com".
String resp = "";
Socket s = null;
            Scanner in = null;
            BufferedWriter out = null;
            try
                URL u = new URL(url);
                int port = u.getPort();
                if(port < 1)
                    port = 80;
                s = new Socket(u.getHost(), port);
                out = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
                out.write(req, 0, req.length() - 1);
                out.flush();
                in = new Scanner(new InputStreamReader(s.getInputStream()));
                while(in.hasNext())
                    resp += in.nextLine() + "\n";
                System.out.println("RESP:" + resp);
            catch(Exception ex)
                resp = ex.toString();
                ex.printStackTrace();
                /*if(in != null)
                    in.close();
                if(out != null)
                    out.close();
                if(s != null)
                    s.close();
            }

But if my request is invalid shouldn't the google server send back an error code?It will only respond once it recognises a complete request. Your request is incomplete. Once you terminate it properly, you will get a response from the server (either the page you wanted, or an error, or something).
