title: What is this code enhancement or practice called? (null == conn) as opposed to (conn == null)
body: <p>I am trying to make a report of some code enhancement, however, i am not too sure what this item is called. Basically, instead of doing a <code>conn == null</code>, it does a <code>null == conn</code> for readability.</p>
  
  <p>Before: </p>
  
  <pre><code>        if (conn == null){            
              if (log.isDebugEnabled()){
                  log.debug("Failed to get a DB Connection");
              }
          }
  </code></pre>
  
  <p>After: </p>
  
  <pre><code>        if (null == conn){            
              if (log.isDebugEnabled()){
                  log.debug("Failed to get a DB Connection");
              }
          }
  </code></pre>
