title: JavaDoc for private / protected methods?
body: <p>Should I write JavaDoc for <em>private</em> or <em>protected</em> methods? And what about <em>private</em> variables?</p>
  
  <p>I see class examples on my Java book and the <em>private</em> variables are JavaDoc'ed.
  So I can't understand if it is a good practice to JavaDoc the <em>private</em> (or <em>protected</em>) methods.</p>
