title: What is the cost of ContainsAll in Java?
body: <p>I discovered <code>containsAll()</code> (a <code>List</code> interface method) during some coding today, and it looks pretty slick.  Does anyone know how much this costs in terms of performance/iterations?</p>
  
  <p>The <a href="http://docs.oracle.com/javase/1.4.2/docs/api/java/util/List.html#containsAll%28java.util.Collection%29" rel="nofollow">documentation</a> didn't offer much in terms of that.</p>
