title: Get all Values from a Map for some Keys in Java/Guava?
body: <p>Is there a smart way to get all Values from a Map given some Keys?</p>
  
  <p>I would like a method like this:</p>
  
  <pre><code>public static &lt;K, V&gt; Collection&lt;V&gt; getAll(Map&lt;K, V&gt; map, Collection&lt;K&gt; keys)
  </code></pre>
  
  <p>or is already a guava way?</p>
