I worked in a number of languages before Perl, so I had the opposite problem.
If memory serves, Java supports hashes and regular expressions (my two favorite Perl features). So rewrite an existing Perl script in Java, and get used to the differences. And, sadly, be prepared to writing a lot more code than you used to.
(Be grateful your employer is letting you cross-train. I'm in the middle of a corporate merger that is fairly brutal...)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
