I just started to learn PERL and i'm getting crazy

I stuck on hashes. I wrote two different codes which are just to learn some staff and hash doesnt work on first one but works on second code

This is first

#!/usr/bin/perl
use strict;
#no strict "vars";
use warnings;


print "Hello Alper\n";
print "43\n";
#SCALARS
my $alper = 35;                 #DEGISKENLER BOYLE TANIMLANIYOR
my $sarper = "What THE fuck";            #NE TUR OLDUKLARI ONEMLI DEGI
+L PERL ANLIYOR
print "$sarper ";                #TANIMLANAN DEGISKEN BOYLE YAZDIRILIY
+OR
print  "$alper \n";                #BOYLE DE YAZDIRILIYOR BIR SONRAKI 
+SATIRA ATLATILARAK
print $sarper," = ",$alper*$alper ,"\n" ;    #BU SEKILDE BIR KAC SEYI 
+BIRDEN YAZDIRABILIRSIN

#ARRAYS
my @array = ("3","2","1","4","alper");        #DIZI BU SEKILDE TANIMLA
+NIYOR
print @array, "\n";                #DIZI BU SEKILDE YAZDIRILIYOR
print $array[1],"\n";                #DIZININ HER HANGI BIR ELEMANI BU
+ SEKILDE YAZDIRILIYOR
print $array[$#array],"\n";            # $#diziadi DIZININ SON ELEMANI
+N INDEX NUMARASINI VERIYOR VE
print $#array,"\n";                #DIZININ ELEMANLARINA 0'DAN BASLAYA
+RAK INDEX ATAN
print $#array+1,"\n";                #DIZININ ELEMAN SAYISINI VERIR
print @array[1,2],"\n";                #DIZININ BIR KAC ELEMANINI BIRD
+EN YAZDIRMAK ICIN KULLANILIR
print @array[1..3]                #DIZININ 1. ELEMANINDAN 3. ELEMANINA
+ KADARINI YAZAR
                        # http://perldoc.perl.org/perlintro.html#Runni
+ng-Perl-programs
                        #kisminda my @sorted kismini calistiramadin bu
+nun cevabini bul
#HASHES

my %bahar = (
    ilk => "1",
    son => "2",
    );

This is second

#!/usr/bin/perl

use strict;
use warnings;

my $ali = 5;

print "$ali\n\n";

my @array = (1, 2, 3, 4, 5);
print $array[$#array]+1,"\n\n";

my %fruit_color = (
       apple  => "5",
       banana => "2",
   );
 
#print  $fruit_color{"banana"},"\n"; 
 
#print $fruit_color{"banana"}*5,"\n";

if ($#array<5){
       print $fruit_color{"banana"},"\n";
       };
[download]

I just cant find what is wrong in first code. Please someone tell me what's the problem in first code?

Thanks in advance
