the code

/**

 * @url http://sites.google.com/site/ganeshgowtham
 * Proxy class (HttpAuthenticateProxy) needs to be used
 * when you are using the internet using the proxy authetication
 */
 
class HttpAuthenticateProxy extends Authenticator {
   String userName = null;
   String password = null;
 
   public HttpAuthenticateProxy(String userName, String password) {
      this.userName = userName;
      this.password = password;
   }
   protected PasswordAuthentication getPasswordAuthentication() {
 
      return new PasswordAuthentication(userName, password.toCharArray());
   }
}

 * http.proxyPort- Proxy Port Number
 * proxyuserName - Proxy Server UserName
 * proxyPwd - Proxy Server Password 
 */
 
public class GoogleSearchExample {
   public static void main(String[] args) throws Exception {
      Authenticator.setDefault(new HttpAuthenticateProxy("proxyuserName", "proxyPwd"));
      System.setProperty("http.proxyHost", "proxyServer");
      System.setProperty("http.proxyPort", "8080");
 
      while (true) {
         String link = "http://www.google.co.in/search?q=ganesh+gowtham";
         URL url = new URL(link);
         URLConnection urlConnection = url.openConnection();
         urlConnection.setRequestProperty(
         "User-Agent",
         "Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.8.1.6) Gecko/20070723 Iceweasel/2.0.0.6 (Debian-2.0.0.6-0etch1)");
         BufferedReader in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
         String inputLine;               
         while ((inputLine = in.readLine()) != null) {
             System.out.println(inputLine);
         }
         in.close();
      }
   }
}

Below code is necessary as without the "User-Agent" Google will return us the java.io.IOException: Server returned HTTP response code: 403 Hence in the below code we try to simulate and request as if we are sending from Browser ( here i used Mozilla )

Above code i used while(true) which means it will go and end-up in infinite loop keeps pinging Google server , So that you can see your name in Google Auto complete in near future .

urlConnection.setRequestProperty(
 "User-Agent",
 "Mozilla/5.0 (X11; U; Linux x86_64; en-GB; rv:1.8.1.6) Gecko/20070723 Iceweasel/2.0.0.6 (Debian-2.0.0.6-0etch1)");
