Implementation

We're going to create an Integrator interface which narrates navigation method and a Container interface which returns the iterate. Concrete classes implementing the Container interface will be in charge to implement Iteratorinterface and apply it.

IteratorPatternDemo, our presentation class will use Names Repository, a material class implementation to feature a Names stored as a collection in Names depot.

Step 1

Create interfaces.

Iterator.java

Container.java

Step 2

Create real class implementing the Container interface. This class has internal class NameIterator implementing the Iterate interface.

NameRepository.java

Step 3

Use the Name Repository to get iterate and issue names.

IteratorPatternDemo.java

Step 4

Verify the output.
