Store array of String or int or list in SharedPreferences android

 SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this);

        JSONArray arr = new JSONArray();

        arr.put("Viren");

        arr.put("Android");

        prefs.edit().putString("key", arr.toString());

        prefs.edit().commit();

        try {

            arr = new JSONArray(prefs.getString("key", "{}"));

            System.out.println(arr.getString(1)); 

        } catch (JSONException e) {

            e.printStackTrace();
