Iterator Design Pattern explained with simple example
by An iterator is an object which allows a developer to easily traverse through a container class. The Iterator design pattern is relatively simple and easy to implement kind of design pattern in which an iterator is used to traverse through a complex container in order to access the elements of the container. This design pattern tries to decouple container classes from the other modules in order to achieve low coupling.
