title: How to add package level comments in Javadoc?
body: <p>I am using <a href="https://en.wikipedia.org/wiki/Checkstyle" rel="noreferrer">CheckStyle</a>, <a href="https://en.wikipedia.org/wiki/FindBugs" rel="noreferrer">FindBugs</a>, and <a href="https://en.wikipedia.org/wiki/PMD_(software)" rel="noreferrer">PMD</a> to validate my Java code. I have fixed almost all the bugs caught by these tools.</p>
  
  <p>I am not able to understand how to write "package comment" which is a bug caught by checkstyle. I have gone through the documentation of CheckStyle, but I don't understand it.</p>
  
  <p>Could someone help me in writing a package level comment in Java?</p>
