package?
package java.lang;
import java.util.Iterator;
/**
* Implementing this interface allows an object to be the target of
* the "foreach" statement.

* @param the type of elements returned by the iterator

* @since 1.5
*/
public interface Iterable {
/**
* Returns an iterator over a set of elements of type T.
*
* @return an Iterator.
*/
Iterator iterator();

We are trying to hack JDK to come up with some striped down version, as long
as our small app can run on top of it, we want to cut unnecessary classes(
even for those classes in JDK) as much as possible to make our runtime as
small as possible.
