Why there is no error raised by compiler?
<p>I just found my compiler allowed me to write below code and did not raised any compile time error. Could anyone please enlighten me!</p>

<pre><code>double y = arcToFindPointOn.getCenterXY().y - arcToFindPointOn.getRadius()*Math.sin(theta);;
</code></pre>

<p>Weird thing about above code line is semi-colon at the very end!</p>

<p>Thanks!</p>
