title: Is there a better way to combine two string sets in java?
body: <p>I need to combine two string sets while filtering out redundant information, this is the solution I came up with, is there a better way that anyone can suggest?  Perhaps something built in that I overlooked? Didn't have any luck with google.</p>
  
  <pre><code>Set&lt;String&gt; oldStringSet = getOldStringSet();
  Set&lt;String&gt; newStringSet = getNewStringSet();
  
  for(String currentString : oldStringSet)
  {
      if (!newStringSet.contains(currentString))
      {
          newStringSet.add(currentString);
      }
  }
  </code></pre>
