title: Should I use less local variables or bet on conciseness?
body: <p>I was lately thinking on using local variables for example:</p>
  
  <p>Should I prefer this:</p>
  
  <pre><code>String firstString = classString.getFirstString();
  String secondString = classString.getSecondString();
  
  ClassGlobal.execute(firstString, secondString);
  </code></pre>
  
  <p>or this;</p>
  
  <pre><code>ClassGlobal.execute(classString.getFirstString(), classString.getSecondString());
  </code></pre>
  
  <p>I personally would prefer the later as its more concise and doesn't require two extra instance variables. But is it a good thing to do ? Am I sacrificing code readability for conciseness ? Or is it just ok to use either one ? </p>
