title: Remove null elements from list
body: <pre><code>List&lt;String&gt; list = new ArrayList&lt;String&gt;();
    list.add("One");
    list.add(null);
    list.add("Two!");
    list.add(null);
    list.add("Three");
    list.add(null);
    list.add("Four");
    list.add(null);
  </code></pre>
  
  <p>I have a list containing <strong>null</strong> elements. Is there any way to remove the <strong>null</strong> elements from the current collection without using any iterations?</p>
