Hi Jim.
If you want to search for items a Hash map is a good option, otherwise you might as well stick with the array. Also are you optimising for speed or memory use? Will the array contain a fixed number of items or change rarely? 

It all depends what you want to do with it.

Hello all:
I have an array of type double....
Double[][] myDoubleArray = new double[2][13];
...I now need to add an additional field.... Should I redimension the array like double[2][13][5] or should I invest in either an arrayList or HashMap?
