title: How to get elements of JSONObject?
body: <p>I have a <code>JSONObject</code> that contains some <code>JSONObjects</code> as follows:</p>
  
  <pre><code>"statistics": {
      "John": {
        "Age": "22",
        "status": "married"
      },
      "Ross": {
        "Age": "34",
        "status": "divorced"
      }
   }
  </code></pre>
  
  <p>Now all I know is the object name(statistics), and <strong>don't know</strong> it's <strong>elements number</strong> or it's <strong>elements names</strong> , So, is there's a way to parse that Object so that I can get it's elements and deal with it (ie. John, Ross) ?</p>
