Answer
Iterators allow safe removal of elements during iteration.
Using an Iterator to traverse a collection allows you to safely remove elements without risking a ConcurrentModificationException. The `remove()` method of the Iterator interface is specifically designed for this purpose. For example, if you want to remove discontinued products from a list, using `Iterator` ensures that you can safely modify the collection while iterating.
