title: Integer.parseInt() Exception handling concept
body: <p><code>Integer.parseInt()</code> in Java is declared to throw <code>NumberFormatException</code>, and it is a checked exception as I think. I have read somewhere that the checked exceptions should be either caught or thrown on the calling method. But we do not need to do it with <code>NumberFormatException</code>. I am confused. Please help me.</p>
