about exception....

[Ganeshkumar cheekati]

In overriding the overriding method has to throw same exception(or)narrower exception(or)no exception.

how can we know which is narrower than other?

Is there any predefined order for exceptions?

[Anoobkumar Padmanabhan]

Hi Ganesh

how can we know which is narrower than other

Go through the Java API for exceptions.
The oder means the hierarchical order in the parent-class hierarchi like,

java.lang.Throwable -> java.lang.Exception -> java.sql.SQLException

[Ganeshkumar cheekati]

thats ok.if we take FileNotFoundException and EOFException
which one is the narrower?

[Jesper de Jong]

FileNotFoundException and EOFException are not in a subclass / superclass relationship (they are both subclasses of IOException), so neither FileNotFoundException is wider or narrower than EOFException nor the other way around.
