How does the Java 'for each' loop work?
...est A: 326,373,762 nanoseconds
Test B: 202,555,566 nanoseconds
B faster by 123,818,196 nanoseconds (37.437545972215744% faster)
I also ran this for an Integer array, and indexes are still the clear winner, but only between 18 and 25 percent faster.
For collections, iterators are faster than index...
