If the superclass throws a checked exception, then the subclass must not throw broader or newer exceptions. However it can throw narrower or lesser exceptions.

If the super class does not throws, then are we allowed to broaden our checked exceptions?

when a object of subclass is created its constructor will definitely call super class constructor so if super class will throw exception subclass must throw too or handle it.

Guys,

read carefully. we are talking about constructor and not simple methods. constructor is something which gets called on object instantion.

so, every child constructor must throw all checked exceptions that super class constructor throws.

do some sample code and try it.

regards,
