To create a TreeSet for a class of objects, the object class must implement the Comparable interface. This interface provides the natural ordering of the objects and allows the TreeSet to handle the sorting of the objects.

However, neither implementing the Set interface nor creating an iterator is necessary to create a TreeSet for a class of objects.
