title: processing/java: cannot invoke length() on the array type boolean[]
body: <p>Surprised that this wasn't already posted. I'm making a for loop, and its worked before but for some reason I can't find the length of a <code>boolean</code> array.</p>
  
  <pre><code>for(int z = 0; z &lt; keyIsFound.length(); z++){
    //do something
  }
  </code></pre>
