i have standalone java program sending data server. using method send request.

            try {                    url url = new url(url + "?prak=" + urlparameters);                 httpurlconnection connection = (httpurlconnection) url                         .openconnection(proxy.no_proxy);                 connection.setrequestmethod("get");                 connection.setconnecttimeout(1000);                 connection.setdoinput(true);                 connection.setdooutput(false);                 connection.setusecaches(false);                 connection.connect();                 int code = connection.getresponsecode();                 if (code >= 200 && code < 300) {                     system.out.println("success");                 } else {                     system.out.println("failed");                 }             }catch (exception e){                 system.out.println("exception occur" + e.getmessage() );              }
