Dear anyone,

I need some serious help. Been trying to figure out inheritance. Was given an assignment to practice inheritance. the code given was.

use v5.10.0;
use warnings;
use strict;

package Animal;

sub new {
    my $class = $_[0];
    my $self = {text => "I am an abstract animal.\n"};
    return bless($self, $class);
}
sub speak {
    my $self = shift;
    print $self->{"text"}
}

package Duck;
our @ISA = qw(Animal); # qw(Animal) je ekvavilentno ("Animal")

sub new {
    return bless({text => "I am a a duck.\n"}, shift);
}

So this is the given code and I'm just supposed to make another package named Cow, Horse, etc. However reading online this is different from the stuff I had and the code doesn't print out anything when running and testing it. From what I gathered it's supposed to print "I am a duck" but it does nothing at all.

I apologize in advance if this is a newbie question but i really can't figure it out tried asking my peers but no one new anything. Thanks in advance for any help.
