title: Passing instance variables to instance methods vs. directly accessing them?
body: <p>Imagine I have a class with an instance member</p>
  
  <pre><code>String instanceMember;
  </code></pre>
  
  <p>Further I have like 4 instance methods accessing this member. Now I am wondering if there is any real pro/con for either directly accessing the instance member from the instance methods or to pass the instance member as a parameter to each of the instance methods?</p>
