title: How can I create an empty java.util.UUID object?
body: <p>I don't know why I can't find the answer to this, but I need to pass a blank UUID object in one of my functions to represent a lack of UUID. What is the UUID analagous form of </p>
  
  <pre><code>val x: "" 
  </code></pre>
  
  <p>, which would be an empty string. I'm essentially trying to get an empty UUID. I tried</p>
  
  <pre><code>UUID.fromString("")
  </code></pre>
  
  <p>but received an error, as you need a valid UUID string.</p>
  
  <p>EDIT: I am implementing this in Scala.</p>
