title: Good way to get *any* value from a Java Set?
body: <p>Given a simple <code>Set&lt;T&gt;</code>, what is a good way (fast, few lines of code) to get <em>any</em> value from the <code>Set</code>?</p>
  
  <p>With a <code>List</code>, it's easy:</p>
  
  <pre><code>List&lt;T&gt; things = ...;
  return things.get(0);
  </code></pre>
  
  <p>But, with a <code>Set</code>, there is no <code>.get(...)</code> method because <code>Set</code>s are not ordered.</p>
