why there are multiple catches for a try block.don't tell me that there can be multiple except..

Answer / reshma

Multiple catch is necessory when the try when the try block
hase statements that raise different types of exceptions.

The single catch block will not be able to handle the
multiple error condition without complex coding. For
example close the database connection and closing of a file
For a particular exception closing of database connection
can be written in one catch block, for another kind of
exception we can close the file in another catch block.
That means if a file is opened and a database connection is
established, we want to release only one resourse at a time
for a particular exception.

When an exception is thrown it traverses through the catch
block until the matching catch block is found.

I hope my understanding is correct......

Answer / puneet khanna

You will need to have this for a basic reason that the
exceptions need to be caught and needed to be displayed if
your try block throws an exception say Array out of bound
exception which is a checked exception and you have only one
catch block which has the object of Exception class then
that Exception will be caught but you will not be able to
handle the particular array out of bound exception. so all
you need is to put all the exception in diff catch statement
which your try block may throw followed by the superclasses
of the exceptiontype subclasses .thus this is how you will
be able to handle each exception by its own way.
