title: What does the "Assigned value is never used" warning mean?
body: <pre><code>unformatted = unformatted.replaceAll(seperator, "\n");
  </code></pre>
  
  <p>Netbeans gives me the warning:</p>
  
  <blockquote>
    <p>The assigned variable is never used</p>
  </blockquote>
  
  <p>What does this mean?</p>
