title: Iterating values in Map
body: <p>I have a map with the following structure:</p>
  
  <pre><code>Map&lt;String,Map&lt;String,UDT&gt;&gt;
  </code></pre>
  
  <p>I am needed to iterate the UDTs extracted from this collection.<br>
  Is there a simpler/neater way to achieve this than iterating values of values in Java 7?</p>
