title: How to break long lines in Java
body: <p>In the <a href="http://www.oracle.com/technetwork/java/javase/documentation/codeconventions-136091.html" rel="nofollow noreferrer">official document of Oracle about coding conventions</a> they write:</p>
  
  <blockquote>
    <p>"Following are two examples of breaking an arithmetic expression. The first is preferred, since the break occurs outside the parenthesized expression, which is at a higher level."</p>
  </blockquote>
  
  <pre><code>longName1 = longName2 * (longName3 + longName4 - longName5)
   + 4 * longname6; // PREFER
  
  longName1 = longName2 * (longName3 + longName4
   - longName5) + 4 * longname6; // AVOID
  </code></pre>
  
  <p>What do they mean by "higher level"? Is it related to the order of evaluation in the expression?</p>
