title: Parse Complex Json Java Mulit-nodes
body: <p>I have a complex JSON with multi nodes:</p>
  
  <pre><code>{
    "List": {
      "Summary": {
        "0": {
          "Id": 163375,
          "city" : "Paris"
  
      },
        "1": {
          "Id": 15541,
          "city" : "London"
  
      },
        "2": {
          "Id": 18459,
          "city" : "Berlin"
  
      }
     }
    }
  }
  </code></pre>
  
  <p>I need Id and City for each node 0,1, 2...</p>
  
  <ol>
  <li><p>How I can parse the information I want? (third node...).</p></li>
  <li><p>How I can iterate? (sometime, I can have 25 or more nodes I mean 0 until 25).</p></li>
  </ol>
  
  <p>Thank in advance for your help!</p>
  
  <p>P.</p>
