Java:
JSONArray arr = new JSONArray(result);
JSONObject jObj = arr.getJSONObject(0);
String date = jObj.getString("NeededString");
Kotlin:
val jsonArray = JSONArray(result)
val jsonObject: JSONObject = jsonArray.getJSONObject(0)
val date= jsonObject.get("NeededString")
- getJSONObject(index). In above example 0 represents index.
