title: Is there a convention, when using Java RMI, to use the dollar sign $ in a variable name?
body: <p>I realize that it is a valid part of a variable name, but I've never seen variable names actually use the symbol $ before.</p>
  
  <p>The Java tutorial says this:</p>
  
  <blockquote>
    <p>Additionally, the dollar sign character, by convention, is never used at all. You may find some situations where auto-generated names will contain the dollar sign, but your variable names should always avoid using it.</p>
  </blockquote>
  
  <p>However, since this is geared toward Java beginners, I'm wondering if in the distributed world, the $ lives on with a special meaning.</p>
