Hello Friend, Hope i can help u in this. Overridden is done to override the method of the base class and overridden with exception have certain rule. 1. if the base class method has thrown any exception the overridden method can throws that exception or subclass of that exception. this rule apply to only checked exception and not to unchecked exception. 2. If the base class method had throws more than one exception like class xyz throws A,B,C then overridden method can throws anyone of these set of exception in subclass. 1. A 2. B 3. C 4. A,B 5. B,C 6. A,C 7. it can neither throw any exception. i hope i am right and ur doubt is also clear upto certain limit.
