Multi-Dimensional Container in Java

Question

I searched around on Google, but I was unable to find any libraries for a multi-dimensional container in Java (preferably one that supports generics as well). I could easily write one (in fact, I have started to), but I was hoping that I would be able to reuse the work someone else has done for the sake of efficiency. I don't necessarily need to provide any sort of additional functionality outside of the "container" realm (AKA, no matrix functionality for example).

Does anybody know of any type of class/library for a multi-dimensional container? Thanks!

Edit: To clarify, yes, I am looking for a Collection of Collections of Collections ... (or int[][][][][], etc). Essentially, a multi-dimensional array.

Answer 1

Can't you use a jagged array (eg int[][])?

You can make it n-dimensional (int[][][][]), but it starts to get silly after a while

Answer 2

Something like this, a Collection of Collections?

Collection<Collection<Object>> multiDimensional = 
                     new ArrayList<Collection<Object>>();

Or something completely different?

Answer 3

Google Collections supports multimaps and multisets (bags). Is that what you mean?
