in reply to Exception Handling in Perl
Program is as follows.
The above program correctly throws the error in try block and it caught in the corresponding catch block.It prints the exception informations. If I commented the catch block statements in the above program,both except block and otherwise block statements are executed.This is what my doubt?use Data::Dumper; #using the Dumper function to get the internal s +tructure use Error qw(:try); #specifying to going to use the try block.This + is enough to use all the # things in it try { #defining a try block my @array; #declaring an array throw Error::Simple "Oops!Array is Empty." unless(@array); #throwi +ng the exception if the array is an empty } catch Error::Simple with { #catching the error my $error=shift; #getting the Error hash print Dumper $error; #printing it in dumper function to know all t +he details such as filename,line number,the error message,package inf +ormations,etc., } except { #defining an except block print "Exception Block\n"; } otherwise { #defining an otherwise block print "Otherwise Block\n"; }
