title: What is the difference between .foreach and .stream().foreach?
body: <p>This is a example:
  code A:</p>
  
  <pre><code>files.forEach(f -&gt; {
      //TODO
  });
  </code></pre>
  
  <p>and another code B may use on this way:</p>
  
  <pre><code>files.stream().forEach(f -&gt; { });
  </code></pre>
  
  <p>What is the difference between both, with <code>stream()</code> and no <code>stream()</code>?</p>
