title: What's the difference between get(int index) and elementAt(int index)?
body: <p>Vector has two methods to get the element at one index.</p>
  
  <pre><code>Vector&lt;Integer&gt; matrix;
  matrix = new Vector&lt;Integer&gt;;
  matrix.get(0);
  matrix.elementAt(0);
  </code></pre>
  
  <p>It seems they are doing the same thing here.</p>
