String.split(".") is not splitting my long String
<p>I'm doing the following:</p>

<pre><code>String test = "this is a. example";
String[] test2 = test.split(".");
</code></pre>

<p>the problem: <code>test2</code> has no items. But there are many <code>.</code> in the <code>test</code> <code>String</code>.</p>

<p>Any idea what the problem is?</p>
