What is the Iterator Design Pattern?
- The Iterator pattern provides you with a uniform way to access different collections of Objects.
- If you get an Array, ArrayList and Hashtable of Objects, you pop out an iterator for each and treat them the same
- This provides a uniform way to cycle through different collections.
- You can also write polymorphic code because you can refer to each collection of objects because they'll implement the same interface.
