title: Iterate through JSONObject from root in json simple
body: <p>I am trying to iterate over a json object using json simple. I have seen answers where you can do a <code>getJSONObject("child")</code> from </p>
  
  <pre><code>{ "child": { "something": "value", "something2": "value" } }
  </code></pre>
  
  <p>But what if I just have something</p>
  
  <pre><code>{
  "k1":"v1",
  "k2":"v2",
  "k3":"v3"
  } 
  </code></pre>
  
  <p>And want to iterate over that <code>json</code> object. This:</p>
  
  <pre><code>Iterator iter = jObj.keys();
  </code></pre>
  
  <p>Throws:</p>
  
  <pre><code>cannot find symbol
  symbol  : method keys()
  location: class org.json.simple.JSONObject
  </code></pre>
