title: JSON Java - is it possible to loop through multiple layers of JSON at once in search of a specific value?
body: <p>Imagine I have a much bigger version of this:   </p>
  
  <pre><code>{
    "name": "a",
    "age": 10,
    "number": 254,
    "spezial": [{
        "name": "vip",
        "age": 12,
        "number": 134
    }, {
        "name": "b",
        "age": 56,
        "number": 934
    }]
  }
  </code></pre>
  
  <p>Now all I want is something like <code>json.containsValue("vip")</code> which returns either true if there is a value "vip" somewere, or false if there isn't.<br>
  I really don't want to loop through each sub Array individually, I would need ten lines of code just to test for a duplicate...<br>
  Thanks for thinking about my problem</p>
