 stringbuilder builder = new stringbuilder();  int statuscode = response.getstatuscode();   if (statuscode == 200) {     httpentity entity = response.getentity();     inputstream content = entity.getcontent();     bufferedreader reader = new bufferedreader(new inputstreamreader(content));     string line;     while ((line = reader.readline()) != null) {       builder.append(line);     }   }
