Java equivalent of Perl's hash

Question

I\'ve been using a lot Perl hashes due to super flexibility and convenient. for instance, in Perl I can do the following:

$hash{AREA_CODE}->{PHONE}->{S         


        

Answer 1

If the hash keys are constant, why won't hash.getAreaCode().getPhone().getStreetAddr() do? Keep in mind that either your getters or your constructors will need to handle default value generation.
