What are some examples of iterator patterns in programming?

Iterator patterns are design patterns that allow sequential access to elements in a collection without exposing the underlying structure. Examples include the Java Iterator, C# IEnumerable, and Python's iterator protocol.

Can you explain how the Java Iterator works?

Sure! The Java Iterator interface provides methods like hasNext() to check if there are more elements, and next() to retrieve the next element in the collection.

What are the benefits of using iterator patterns?

Using iterator patterns promotes loose coupling, allows for easy traversal of complex data structures, and enhances code readability.

Are there any drawbacks to using iterator patterns?

One drawback is that they can introduce additional complexity, especially if the collection is modified during iteration, which can lead to concurrent modification exceptions.
