title: Convert String array to Char array
body: <p>I'm extremely stuck here.
  How would I convert a String array to a Char array?</p>
  
  <p>I know of:</p>
  
  <pre><code>char[] myCharArray = myStringArray.toCharArray();
  </code></pre>
  
  <p>But obviously that doesn't work.</p>
  
  <p>How would I do this?</p>
