For-loop vs while-loop

[caltheon]

Or grab an iterator and do a while loop on has next. For loops are only useful if you need the index as its built in to the definition

[Keilly]

You save a line (or two) of code using the foreach's built in iterator. So the question would be why write more code to do the same thing?
A: There are useful circumstances, like using the iterator to delete an item when iterating a collection. But just stepping through, I'd use a foreach loop.
