Do Multidimensional arrays work like a hash in Perl?

[philthee]

Perhaps can they? would be better

Say i have a file

One 232
Two 323
Three 555
One 231

can they work so as to have my code read in each line as a key and value pair, and then i can catch any instances of a key appearing twice (in this case 'One') and do something with it?

it can be done, but you'd need more than an array. have a look at the Map interface.

in reply to your question:
no, java arrays are only indexed with numbers. they do not work as hashes.
