title: Collections.nCopies() vs. For-loop Initialization
body: <p>I recently found out that you can initialize Lists in Java by calling the <code>Collections.nCopies()</code>method rather than using a for-loop. But that got me wondering, is there a performance advantage/disadvantage in using this method over a for-loop or is it just a simpler way of doing the same thing?  </p>
