Identifying last loop when using for each

Question

I want to do something different with the last loop iteration when performing \'foreach\' on an object. I\'m using Ruby but the same goes for C#, Java etc.

Answer 1

The foreach construct (in Java definitely, probably also in other languages) is intended to represent the most general kind if iteration, which includes iteration over collections that have no meaningful iteration order. For example, a hash-based set does not have an ordering, and therefore there is no "last element". The last iteration may yield a different element each time you iterate.

Basically: no, the foreach construct is not meant to be used that way.
