Multi-valued hashtable in Java

Question

Is it possible to have multiple values for the same key in a hash table? If not, can you suggest any such class or interface which could be used?

Answer 1

Rather than give yet another multipmap answer, I'll ask why you want to do this?

Are the multiple values related? If yes, then it's probably better that you create a data structure to hold them. If no, then perhaps it's more appropriate to use separate maps.

Are you keeping them together so that you can iterate them based on the key? You might want to look for an alternative indexing data structure, like a SkipList.
