title: List item with double quotes
body: <p>I want list item should be with double quotes.
  i tried like this :</p>
  
  <pre><code>List&lt;String&gt; langList = new ArrayList&lt;&gt;();
      for (Language obj : language) {
          langList.add(obj.getCode());
      }
  JSONObject where = new JSONObject();
  try {
      JSONObject languages = new JSONObject();
      languages.put("$in", langList);
      where.put("languages", languages);
      } catch (JSONException e) {
          e.printStackTrace();
      }
  </code></pre>
  
  <p>result of <code>langList</code> is : <code>"[en, ta, hi]"</code>
  and I added double quotes for items using <code>langList.add("\"" + obj.getCode() + "\"");</code></p>
  
  <p>now, It returns the result is : <code>"[\"en\", \"ta\", \"hi\"]"</code></p>
  
  <p>I don't want outside double quotes also.</p>
  
  <p>am expecting result is : <code>["en", "ta", "hi"]</code></p>
