title: Get Set of entries from a Map
body: <p>Given a map such as:</p>
  
  <pre><code>Map&lt;String, Integer&gt; = new Hashmap&lt;String, Integer&gt;;
  </code></pre>
  
  <p>How can I get a <code>Collection&lt;Integer&gt;</code> (any implementation of Collection would do) of the entrySet?  Doing <code>.entrySet()</code> doesn't seem to work.</p>
