How can I use Comparator while using an Iterator? (Java)

For example:

Consider I created a collection (not any of the defined ones in existing java libraries like, java.util.ArrayList, java.util.List, etc..). it's known as a SortedArrayCollection col; It holds Book objects, and I want to sort them by "title". Also, I have created a method that returns an Iterator within this collection.

Now consider I created a class that implements the Comparator interface and sorts them by title, lets call that TitleComparator.

In my test Driver lets say that I used an Iterator to iterate

Iterator it = col.iterate();

How do I sort with the comparator? Without using collections.sort() or Arrays.sort(),
