Dude, the way you teach this it's insane, thanks for making it so understandable.

i am learning my full design pattern syllabus in OOP module from your videos. thx so

OOP is so smart sometimes. I would have never come up with 4:43 where you define the viable iterators for a class by creating fields of type iterator within that class. So clever imo.

Thank You. Understood the behind the scenes of iterator pattern.

Program to an interface. In that way we can add features instead modifying it.

Hi! I assume there is a mistake in the schema. Method createIterator() from the interface IterableCollection does not have any arguments. However, It returns an instance of type Iterator.

How is current.setVisited(true) does not affect other iterators working on the same collection???
