Welcome to my Iterator Design Pattern Tutorial! The iterator design pattern allows you to access objects that are stored in many different collection types.
You do this by creating a common interface that these classes share. Then you have them provide you with an iterator that allows you to traverse the objects they contain.
Because they all share a common interface you can treat them polymorphically and eliminate a lot of duplicate code.
