title: Print out elements from an Array with a Comma between the elements
body: <p>I am printing out elements from an <code>ArrayList</code> and want to have a comma after each word except the last word.</p>
  <p>Right now, I am doing it like this:</p>
  <pre><code>for (String s : arrayListWords) {
      System.out.print(s + &quot;, &quot;);
  }
  </code></pre>
  <p>It prints out the words like this:</p>
  <pre><code>one, two, three, four,
  </code></pre>
  <p>The problem is the last comma. How do I solve it?</p>
