title: How to name a variable that is a copy of a parameter?
body: <p>I have a method that will process a <code>Collection&lt;Nodes&gt;</code> that is passed in as a parameter. This <code>Collection</code> will be modified, therefore I thought it would be good to first make a copy of it. How do I name the parameter and local variable, e.g. <code>nodes</code> in the example below?</p>
  
  <pre><code>List&lt;Nodes&gt; process(Collection&lt;Nodes&gt; nodes) {
    List&lt;Nodes&gt; nodes2 = new ArrayList&lt;&gt;(nodes);
    ...
  }
  </code></pre>
  
  <p>As another example consider the following where the variable is an <code>int</code> parsed from a <code>String</code> parameter:</p>
  
  <pre><code>public void processUser(final String userId) {
    final int userId2 = Integer.parseInt(userId);
    ...
  </code></pre>
