We now introduce collection classes and control flow techniques to traverse such collections. Specifically we examine the ArrayList class and how to use the class to manage and manipulate data.

We will look at adding a menu to the Shop project that we explored in labs. New concepts include sentinel-based loops, switch statements and the Scanner class.

Use BlueJ Notebook class to gain basic experience with the ArrayList collection class. Explore some of its methods by generating and manipulating test data. Gain experience in looping using for, enhanced for, while, do-while and iterators.
