import com.google.gson.JsonArray;
import com.google.gson.JsonElement;
import com.google.gson.JsonObject;

public class USCities extends HttpServlet {
private static final long serialVersionUID = 1L;

public USCities() {
super();
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request,response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

String start = request.getParameter("start");
String limit = request.getParameter("limit");

PrintWriter out = response.getWriter();
response.setContentType("text/html");

CityInformation cityInformation = new CityInformation();
ArrayList<City> cityList = cityInformation.getCities(start,limit);
//System.out.println("cityList----------"+cityList);
Gson gson = new Gson();
JsonArray arrayObj = new JsonArray();
for(int i=0;i<cityList.size();i++){
//System.out.println("cityList-----1-----"+cityList.get(i).toString());
City city = cityList.get(i);
JsonElement cityObj = gson.toJsonTree(city);
// System.out.println("Json Element----"+cityObj);
arrayObj.add(cityObj);
}

JsonObject myObj = new JsonObject();
myObj.addProperty("success", true);
myObj.add("cityList", arrayObj);
myObj.addProperty("totalCount", limit);

out.println(myObj.toString());
out.close();

}
