title: Java programming- error tracking
body: <p>I have a raffle draw program that used to have many commands and components, etc.
  But I would like to make it a lot simpler by omitting many commands or components such as buttons or labels.
  When I tried to do so, errors arose (42 errors) all of which say: </p>
  
  <pre><code>error: class, interface or enum expected.
  </code></pre>
  
  <p>Can somebody help me track down these errors?</p>
  
  <p>BTW, here's my code (UPDATED):</p>
