Get Data From Nested Array JSON Without Name Android

Question

I'm trying to get the value of elevations from JSON in android but in the log nothing is shown. This JSON is a nested array, I'm still new toth parsing JSON in android.

This is what the JSON looks like :

This is my code :

try {
      JSONObject responseObject = new JSONObject(result);
      JSONArray elev = responseObject.getJSONArray("resourceSets");
      JSONArray el = elev.getJSONObject(1).getJSONArray("elevations");

      for(int i=0; i<=el.length();i++){
           Log.d("EL",el.toString());
      }
}
catch (Exception e){
    e.printStackTrace();
}

try like below: (problem in your code is you are getting "elevations" directly without getting "resources" array)

try {
      JSONObject responseObject = new JSONObject(result);
      JSONArray elev = responseObject.getJSONArray("resourceSets");
      JSONArray el_resources = elev.getJSONObject(0).getJSONArray("resources");
      JSONArray el = el_resources.getJSONObject(0).getJSONArray("elevations");

      for(int i=0; i<=el.length();i++){
           Log.d("EL", el[i].toString()); // also get index from array then print it
      }
}
catch (Exception e){
    e.printStackTrace();
}

wah thank you, its work. Can you tell me why that JSONObject at index 0?

JSONObject at index 0 means we are getting 0th index from array but if you have multiple json array then you can for loop it
