What are the differences between iterator patterns and other design patterns?

What are the differences between iterator patterns and other design patterns?

Iterator patterns are specifically designed to traverse collections without exposing their underlying structure, while other patterns like Singleton or Factory focus on object creation and management.

Can you give me an example of an iterator pattern in use?

Sure! In a collection of books, an iterator pattern allows you to loop through each book without needing to know how the collection is stored.

How do iterator patterns compare to observer patterns?

Iterator patterns focus on accessing elements sequentially, while observer patterns are about notifying multiple observers about state changes.

Are there any drawbacks to using iterator patterns?

Yes, one drawback is that they can add complexity to the code, especially if the collection is modified during iteration.
