Answer / anjan singh

while overriding, you must keep in mind that the exception
being thrown by overriding method(method in subclass)
should not throw a broader exception than what is already
thrown by method in super class. one exception is that, you
can always throw RuntimeException from method in subclass.

Answer / jeevan

It is a good programming practice to have only a sub set of
checked exceptions classes from the throws clause of the
inherited method of the superclass.


Here in the above example E2,E3 exception are not a subset
of the exception classes of the inherited method

Answer / sunita

Overriding methods cannot change the signature of the
overridden method. but runtime exception r not present in
signature so u can only add the runtime exception in
overriden method.
