title: Good uses for Apache CollectionUtils
body: <p>I found the <a href="http://commons.apache.org/collections/apidocs/org/apache/commons/collections/CollectionUtils.html" rel="nofollow noreferrer">CollectionUtils</a> class a year or so ago and a few of the methods like, collect, and transform seem really cool, however, I have yet to find a use where it would not by syntactically cleaner and\or easier to just write the logic with a simple loop. </p>
  
  <p>Has any found a unique\useful use for these methods (transform, predicatedCollection, collect, etc) e.g. the methods that take a transformer or predicate as an argument?</p>
