Hi all I need some help, I try to implemented a cache using TableMap and Hashtable , etc but neither Map or Set interface allow duplicate. I need a structure that allow duplicate key (like Destination airport, SFO) I don't want to use list,vector or array because need to be fast access. Some advice !!! PLEASE
