Java Iterator & Inner class

After reading this chapter and engaging in the embedded activities and reflections, you should be able to:

• Describe the iterator design pattern.
• Differentiate between the Java Iterable and Iterator interfaces.
• Declare, specify and test Iterable ADTs.
• Write a Java class that implements the Iterable interface.
• Write a Java class that implements the Iterator interface.
• Appreciate that an inner class (non-static) Iterator implementation is an instance member and has access to the instance members of the outer class.
• Understand the data encapsulation resulting from private inner classes.
