Java memory collection usage
<p>I have a try catch and finally block like this.</p>

<pre><code>Client client = new Client();
try {
   ...
}
catch {
   ...
}
finally {
   client = null;
}
</code></pre>

<p>I would like to ask if <code>client = null</code> is necessary to wipe out memory use for client object if exception occurs.</p>
