In fact, it's possible with all classes that implement Iterable; the 
Collection interface extends Iterable so you are correct, but it goes 
further than just Collection.

The only classes in java.* and javax.* that implement it seem to 
implement Collection (you'd think CharSequence as well, and perhaps even 
Map and/or Enumeration or all the legacy classes that provide an 
Enumeration, but no), but third party libraries can in principle 
implement it separately.

The foreach syntax can also be used with arrays, including arrays of 
unboxed primitives, even though using reflection on an array (e.g. (new 
Object[3]).getClass().getInterfaces();) only shows it implementing 
Cloneable and Serializable, not Iterable.
