Please provide an example how to sort ArrayList?
public static JSONArray sortJSONArrayAlphabetically(JSONArray jArray) throws JSONException {
if (jArray != null) {
// Sort:
ArrayList<String> arrayForSorting = new ArrayList<>();
for (int i = 0; i < jArray.length(); i++) {
arrayForSorting.add(jArray.get(i).toString());
}
Collections.sort(arrayForSorting);
// Prepare and send result:
JSONArray resultArray = new JSONArray();
for (int i = 0; i < arrayForSorting.size(); i++) {
resultArray.put(new JSONObject(arrayForSorting.get(i)));
}
return resultArray;
}
return null; // Return error.
}
this method fail
