Method overriding and exceptions
<p>I was going through SCJP 6 book by Kathe sierra and came across this explanations of throwing exceptions in overridden method. I quite didn't get it. Can any one explain it to me ?</p>

<blockquote>
  <p>The overriding method must NOT throw checked exceptions that are new 
  or broader than those declared by the overridden method. For example, a 
  method that declares a FileNotFoundException cannot be overridden by a 
  method that declares a SQLException, Exception, or any other non-runtime 
  exception unless it's a subclass of FileNotFoundException.</p>
