title: Code line wrapping - how to handle long lines
body: <p>I'm facing a particular line that is 153 characters long. Now, I tend to break things after 120 characters (of course, this is heavily dependent on where I am and the local conventions.) But to be honest, everywhere I break the line just makes it look bad. So I'm looking for some ideas on what I should do for it.</p>
  
  <p>Here's the line:</p>
  
  <pre><code>private static final Map&lt;Class&lt;? extends Persistent&gt;, PersistentHelper&gt; class2helper = new HashMap&lt;Class&lt;? extends Persistent&gt;, PersistentHelper&gt;();
  </code></pre>
  
  <p>I'm open to both ideas about how/where to break the line (and why), as well as ways to shorten the line itself.</p>
  
  <p>We're not a Java shop, and there aren't local conventions for this sort of thing, or obviously I would simply follow them.</p>
  
  <p>Thanks!</p>
