title: Copy a java list with a limit of entries
body: <p>I would like to create a new <code>List&lt;Object&gt;</code> from a simple <code>List&lt;Object&gt;</code> only for the 20 first  entries.</p>
  
  <pre><code>//my first array
  List&lt;Staff&gt; staffs = new ArrayList&lt;Staff&gt;();
  
  staffs.add(new Staff(...));
  staffs.add(new Staff(...));
  staffs.add(new Staff(...));
  staffs.add(new Staff(...));
  
  
  List&lt;Staff&gt; second = magicMethodForClone(staffs,20);
  </code></pre>
  
  <p>I'd like to know if a method like <code>magicMethodForClone</code> exists or not.</p>
  
  <p>Thank you</p>
