*Friends, I had a doubt regarding Exception class hierarchy. If anyone
thinks of a solution kindly reply back.*
*We know subclasses always have an extended functionality of superclass-
i.e. all functions of superclass are necessary to be there in subclass too
then the problem is*
Suppose my code is somewhat like:
try
{
//code here
}
catch( IOException e )
{}
This works fine, now we have IOException subclass of superclass
Exceptionthen how come on replacing IOException by Exception also, the
code has no
more problem.I know that Exception is a generalised class but IOException
being a subclass must not only have functionality of Exception class but
also added specific functionality.
