title: Add elements to an arraylist in Java with a 'for' loop where the element name has an increasing number
body: <p>I have an arraylist where I want to add elements via a <em>for</em> loop.</p>
  <pre><code>Answer answer1;
  Answer answer2;
  Answer answer3;
  
  ArrayList&lt;Answer&gt; answers = new ArrayList(3);
  
  for (int i=0; i&lt;3; i++)
  {
      answers.add( /* HOWTO: Add each of the answers? */ );
  }
  </code></pre>
  <p>How would this go if I have, let's say, 50 <em>Answer</em> elements?</p>
