Hi,
im having a small problem. im completely stuck and i dont know how to get unstuck...
i have some code here:
#!/usr/bin/perl
use strict;
use warnings;
package Vehicle;
sub new {
my $class = @_;
my $self = {
_engine => "I have an engine.",
_wheel => "I have wheels.",
_door => "I have doors."
};
bless $self, $class;
return $self;
}
package Private;
sub new {
my $class = @_;
my $self = {
_Vehicle => new Vehicle(),
_private => "I am private"
};
bless $self, $class;
return $self;
}
package Family;
sub new {
my $class = @_;
my $self = {
_Private => new Private(),
_passengers => "I carry 5 passengers",
_goods => "I carry 50lbs"
};
bless $self, $class;
return $self;
}
package main;
my $car = new Family();
foreach $car (sort keys my %hash) {
print "$car => $hash{$car}\n";
}
im trying to learn inheritance packages here and i cant seem to get a hold of it. what im trying to do is print out something from one package and all it's inheritances too...
does anyone get what i mean?
my output is nothing. no errors, nothing. just blank.
i was hoping to get printed, this:
I have an engine
I have doors
I have wheels
I am private
I carry 5 passengers
I carry 50lbs
