Behind scenes of enhanced for loop
The for-each loop can be used with identifiers whose type is Iterable or its an Array type.
From JLS
The Expression must either have type Iterable or else it must be of an array type (§10.1), or a compile-time error occurs.
Now that following in the java.lang.Iterable javadoc
All Known Subinterfaces:
BeanContext, BeanContextServices, BlockingQueue, Collection, List, Queue, Set, SortedSet
