Creating static, nested associative arrays in Java -


i have data model represent in java class, defined nested associative array. want able create instance of object , either reference key-value pairs name, or iterate on them. if going in python or javascript, nested associative array might this:

sandwiches = {     "ham sandwich": {         "bread": "white",         "meat": "ham",         "condiment": "mustard"     },     "blt": {         "bread": "rye",         "meat": "bacon",         "condiment": "mayo"     },     ... }

is there quick , easy way create object in java? assume nested hashmap looking for, there not seem simple one- or two-lined method creating object using native java libraries. if there not exist way standard java libraries, 3rd-party tools ideal this?
