title: How to add values to Double[] arraylist
body: <p>I created this arrayList:</p>
  
  <pre><code>Double[] arrayOfNumbers = new Double[List.size()];
  </code></pre>
  
  <p>And I try to add it numbers with this:</p>
  
  <pre><code>arrayOfNumbers.add(0.9);
  </code></pre>
  
  <p>This gives me an error message that says:</p>
  
  <blockquote>
    <p>Cannot invoke add(double) on the array type Double[]</p>
  </blockquote>
  
  <p>So, how can I add that value in this <code>Double[]</code> arraylist?</p>
