title: convert comma separated string to list without intermediate container
body: <p>I need to convert comma separated string to list of integers. For example if I have following string</p>
  
  <pre><code>String numbersArray = "1, 2, 3, 5, 7, 9,";
  </code></pre>
  
  <p>Is there a way how to convert it at once to <code>List&lt;Integer&gt;</code>?</p>
  
  <p>Now i see only one way to do it.</p>
  
  <pre><code>List&lt;String&gt; numbers = Arrays.asList(numbersArray.split(","));
  </code></pre>
  
  <p>And then</p>
  
  <pre><code>List&lt;Integer&gt; numbersInt = new ArrayList&lt;&gt;();
  for (String number : numbers) {
      numbersInt.add(Integer.valueOf(nubmer));
  }
  </code></pre>
  
  <p>I'm curious is there a way how to miss part with <code>List&lt;String&gt;</code> and at the first onset convert it to <code>List&lt;Integer&gt;</code></p>
