How does a for each loop guard against an empty list?

Question

I read on http://www.leepoint.net/notes-java/flow/loops/foreach.html. the for each equivalent to

for (int i = 0; i < arr.length; i++) { 
     type var = arr[         


        

Answer 1

Yes, it is equivalent.

If the list is empty, the for-each cycle is not executed even once.
