title: java howto ArrayList push, pop, shift, and unshift
body: <p>I've determined that a Java <code>ArrayList.add</code> is similar to a JavaScript <code>Array.push</code></p>
  
  <p>I'm stuck on finding <code>ArrayList</code> functions similar to the following</p>
  
  <ul>
  <li><code>Array.pop</code></li>
  <li><code>Array.shift</code></li>
  <li><code>Array.unshift</code> I'm leaning toward <code>ArrayList.remove[At]</code></li>
  </ul>
