title: Jsoup - how to check if Element is of specific class?
body: <p>This is my Element code:</p>
  
  <pre><code>&lt;tr class="footer"&gt;...&lt;/tr&gt;
  </code></pre>
  
  <p>In the table there are also other rows with other classes and I process each of them. How can I know if this processed <code>tr</code> element has "footer" class?</p>
