Iterator have to be utilized Each time we wish to iterate things in all Assortment framework executed interfaces, for instance Established, Listing, Queue, and Deque, and also all Map interface carried out classes. The only cursor accessible for the entire selection framework is definitely the iterator.

The 3 "Selection check out procedures" on Maps characterize the fact that Maps is often viewed as Collections (of keys, values, or pairs) (keySet, entrySet, and values). Though it's theoretically possible to find out an inventory like a Map mapping indices to items, this has the unlucky facet impact of fixing The main element affiliated with every single element while in the Record before the deleted member. This can be the rationale why Selection cannot be produced to extend the Map Interface either.

Iterator: Because it is often placed on any Assortment item, It's a universal iterator. We can execute equally study and remove operations working with Iterator. It truly is an enhanced Variation of Enumeration that provides the chance to remove a component through the checklist.
