It always depends upon your circumstances.
Array Pros
- Small code.
- Rapid random access and sequenctial access.
- No storage overhead (inter-element storage).
Array Cons
- Only efficient in a fixed size
- Sorting elements can be expensive. Especially since array don't hold an intrinsic
order.
- requires a large contiguous memory allocation which can be innefficient to page in
and out of main memory.
- no added-value fuctionality available.
Collections Pros.
- under the covers the collection can be stored in an efficient method
to match the retrieval models.
- Added-value functionality can be added in an OO fashion which encapsulates code
nicely.
- Better capability for scaling.
- incremental allocation of resources.
Collections Cons
- Complexity of implementation
- performance is worse than array for small amounts of data which fit the array
requirements.
- Storage overheads on some effective indexing/ordering models can be quite high.
