What Kind Of Array Is This?

[H100]

N00b question, sorry... I'm porting some Perl code to Java, and I came across code like this:

$d['A3'] = 63.6;
$d['B1'] = 34.6;
$d['C4'] = 7.2;
$d['B'] = 49.2;

My first assumption was that this is something like a hashtable or associative array, where the value (for instance) of $d['C4'] is 7.2. However, any time I try to run the Perl script and print the value of any item in the array based on what I thought was the "key" ('C4'), I always get the value of the last item listed - in the case above, everything returns 49.2.

Can anyone explain this construct? I've searched online and found nothing.

Thanks in advance for any help!

the code you posted is not any kind of perl code. If it is a hash the keys are wrapped in curly brakets {}, not square brackets []:


$d{'C4'} = 7.2;

arrays can only use a number inside the square brackets to access the element that the number is the index of:

$d[4] = 7.2;

or a scalar that is a number:

$i = 4;
$d[$i] = 7.2;

Kevin, thank you so much for your quick reply. Believe me, that possibility actually crossed my mind... scary...

Unless there is some kind of Perl extension out there that allows for this weird type of array notation, I'm going to have to consider the legacy code flawed and scrap it.

Thanks again!
