Nested get performance
<p>In Java, is there a performance hit if i continually use nested get to retrieve values? For instance:</p>

<pre><code>String firstname = getOffice().getDepartment().getEmployee().getFirstName();
String lastname = getOffice().getDepartment().getEmployee().getLastName();
String address = getOffice().getDepartment().getEmployee().getAddress();
</code></pre>

<p>VS:</p>

<pre><code>Employee e = getOffice().getDepartment().getEmployee();
String firstname = e.getFirstName();
String lastname = e.getLastName();
String address = e.getAddress();
</code></pre>

<p>Would the 2nd version be faster because it has less 'jumps'?</p>
