JavaでJSON-lib APIを使用して配列をJSON配列に変換するにはどうすればよいですか?

import net.sf.json.JSONArray;
import net.sf.json.JSONSerializer;
public class ConvertArrayToJSONArrayTest {
   public static void main(String[] args) {
      <strong>Object[]</strong> objArray = new <strong>Object[] </strong>{
               "Array to JSON Array",
                new Integer(10),
                new Long(30),
                new Double(14.26),
                true,
                new char[] {&#39;X&#39;, &#39;Y&#39;, &#39;Z&#39;}
      };
      <strong>JSONArray </strong>jsonArray = <strong>(JSONArray)JSONSerializer.toJSON</strong>(objArray);
      System.out.println(jsonArray.toString(3));<strong> //pretty print JSON</strong>
   }
}

<strong>[
   "Array to JSON Array",
   10,
   30,
   14.26,
   true,
   [
      "X",
      "Y",
      "Z"
   ]
]</strong>
