Does the iterator provide a sequential order when traversing elements?

An iterator in Java and Android typically provides a sequential traversal order of elements if the collection being iterated supports ordering. For example, an iterator for ArrayList or LinkedList will return elements in the order they were added. However, for collections that do not guarantee order (such as HashSet), the iterator may return elements in an arbitrary order. Therefore, the sequential order depends on the specific implementation of the collection, not on the iterator itself.
