Why are parentheses used when declaring a textview
<p>I'm fairly new to android.  I've got experience with c# and java but I can't figure this out.</p>

<p>I know how to use it.  I've written a couple apps already.  It's probably really simple but I don't understand this.  Why is (TextView) in parentheses.</p>

<p>I've searched the sdk documentation and afaik it doesn't mention this.</p>

<pre><code>TextView example = (TextView) findViewById(R.id.example);
</code></pre>
