title: Why were applets deprecated in JDK 9?
body: <p>I have recently read in an article posted by Oracle that they are going to mark the <code>Applet</code> class as deprecated in JDK 9. I have little experience with applets; I have only written some to understand the basics.</p>
  
  <p>Why are they unpopular, and what is the main reason for their deprecation?</p>
