I want to put a marker on the NAVER API map with latitude hardness parsed by Json. (STRING TO DOBLE)

I'm trying to take a marker using Naver API map, but the value of the marker is double type, so it can't

double LNG = Double.parseDouble(longitude.toString());

I tried to change it to Double and put it in, but there was an error.

longitude = new ArrayList<>();
latitude = new ArrayList<>();

I'm going to take a marker using the longitude and lateitude declared as ArrayList.

    double LNG = Double.parseDouble(longitude.toString());
    double LAT = Double.parseDouble(latitude.toString());

    Marker marker = new Marker();
    marker.setPosition(new LatLng(LAT, LNG));
    marker.setMap(naverMap);

The code looks like this. Just in case, I will put the json parsing code as well.

try {

        JSONObject Land = new JSONObject(result);
                    JSONArray jsonArray = Land.getJSONArray("Response");
            for(int i = 0 ; i<jsonArray.length(); i++){
                JSONObject subJsonObject = jsonArray.getJSONObject(i);

            String sLAT = subJsonObject.getString("latitude");
            String sLNG = subJsonObject.getString("longitude");

            latitude.add(sLAT);
            longitude.add(sLNG);
             }
        } } catch (JSONException e) {
            e.printStackTrace();
        }

I look forward to hearing from you

Transforming the List does not convert all elements in the list to Double.

Declare latitude, longitude as a list containing double as shown below.

List<Double> latitude = new ArrayList<>();
List<Double> longitude = new ArrayList<>();

Modify the code that handles json.

Double sLAT = subJsonObject.getDouble("latitude"); //String sLAT = subJsonObject.getString("latitude");
Double sLNG = subJsonObject.getDouble("longitude"); //String sLNG = subJsonObject.getString("longitude");
