title: private static fields, should names start with underscore?
body: <p>I came across a list of naming convensions, wondering how I should name my non-final private static fields. Link <a href="http://www.appperfect.com/support/java-coding-rules/namingconvention.html#rule38" rel="nofollow"><b>here</b></a>, Rule #38.</p>
  
  <p>The resource states that <strong>non-final private static variable names should start with an underscore</strong>.</p>
  
  <p>However, I have personally never come across any Java-code where this rule is enforced.<br />Is this bogus, or should I adhere to it?</p>
