If you know how to do it in an ArrayList or a List then you know how to do
it in its generic class :)

Notice that the functionality that you are familiar with comes from Iterable
class.  The only difference is that you do not know how it is stored.

Do you know the for () loop?

What exactly is an Iterable?

You can iterate through a loop using an Iterator and getting the
iterator.next() the way a List would get the element at index i.

Instead of
  for ( int i = 0; i < yourList.size(); ++i )

it would look more like
  for ( Iterator <T> iter = yourIterable.iterator(); iter.hasNext(); )

There is also the new style for () that looks pretty much the same for either
idiom:

  for ( T t : collection )

Have you tried actually reading your textbook and lecture notes for these
concepts?

Iterable and every other part of the Java API is documented at
<http://java.sun.com/javase/6/docs/api/>

Get to know the API docs.  Get to love the API docs.

Actually, if you only have an Iterable, then there is no concept of
order. For there to be a concept of order, you much either have a
SortedSet or a List

Please restate your question so that it makes sense... What exactly
are you trying to do?
