title: how to reduce length of UUID generated using randomUUID( )
body: <p>I have a short utility in which I am generating a UUID using randomUUID(). </p>
  
  <pre><code>String uuid = UUID.randomUUID().toString();
  </code></pre>
  
  <p>However, the uuid generated is too long which is 36 in length.</p>
  
  <p>Is there anyway I can reduce the length of the UUID from 36 to near to 16 or 16 ?</p>
