What does it mean when you try to print an array or hash and you see the following; Array(0xd3888) or HASH(0xd3978)?

EXAMPLE

CODE

my @data = (  
['1_TEST','1_T','1_TESTER'],  
['2_TEST','2_T','2_TESTER'],  
['3_TEST','3_T','3_TESTER'],  
['4_TEST','4_T','4_TESTER'],  
['5_TEST','5_T','5_TESTER'],  
['6_TEST','6_T','^_TESTER']  
);  

foreach my $line (@data) {  
   chomp($line);  
   @random = split(/\|/,$line);  
   print "".$random[0]."".$random[1]."".$random[2]."","\n";  
}

RESULT

ARRAY(0xc1864)  
ARRAY(0xd384c)  
ARRAY(0xd3894)  
ARRAY(0xd38d0)  
ARRAY(0xd390c)
