    使用json-lib很简单，实例代码：

     public class JsonLib {
   public static void main(String[] args) {
        String json = "[]";//你上面的字符串
       JSONArray jsonArray = JSONArray.fromObject(json);
       Object array = JSONArray.toArray(jsonArray);
       System.out.println(array);
       System.out.println(Arrays.asList((Object[]) array));
   }
}

    需要导入jar，详细的json-lib的使用过程参考:http://www.cnblogs.com/sunzn/archive/2013/02/12/2910241.html
