not a pro in java. but in hash table data structures, any integers are 99% of the time unique. this is bc they are used as keys. to get the names and such. so usually one to one. one key. one value. if you have a hash set up so that it is n = key, and you have a collision, that should mean that you are inserting the Same data. avoid collision. hope this helps
