	* Iterable is a generic approach to getting an iterator. It enables an object to support for-each syntax. It is not concerned with how the iterator works, where it starts or stops, etc. It just returns the iterator. If you implement Iterable<E> you just need to be able to provide an Iterator<E>.		* Iterable is a generic approach to getting an iterator. It enables an object to support for-each syntax.

In Java, there are two mechanisms to allow you to deal with iteration:
* Iterable is a generic approach to getting an iterator. It enables an object to support for-each syntax. It is not concerned with how the iterator works, where it starts or stops, etc. It just returns the iterator. If you implement Iterable<E> you just need to be able to provide an Iterator<E>.
* Iterator is a simple wrapper class (like a Scanner object) that just supports a few operations for getting the next item in an object/collection
