In this activity, you will implement a small subset of your course project functionality using the MVC architecture pattern.
Activity Description
Consider where in your application you need to present the user with access to a collection of data (e.g. a list). For example, in the Vintage Sounds demo application we may want the user to be able to step through the list of instruments in inventory.
For this assignment, you will need five classes:
- The application class with the main method
- A controller class
- A model class (for example, in Vintage Sounds, Instrument)
- A second model class containing an ArrayList of model class objects (e.g., InstrumentList)
- A view class (e.g., InstrumentUI)
When the application is launched:
- The main method creates an instance of the controller class.
- The controller class creates the list of model objects, both the ArrayList and its members.
- The controller class creates and shows an instance of the view class. The view class should include JTextFields to display data accessed from the model objects.
- When the view class is first shown, it should display data from the object in the first position of the ArrayList.
- The view class should include buttons to allow a user to move backwards or forwards through the objects in the ArrayList.
- The user may also change any of the fields in a particular object, delete an object, add a new object, or exit the application.
- All of the behavior above should be mediated by the controller class. In other words, the view class should only communicate with the controller, and the controller alone manages interactions with the model objects.

The above program needs to compile in next beans with functionality when the following happens:
- Populate the ClubList ArrayList (both Team Name and Team Mascot fields)
- Code programmed in the “Club Cntl” class to execute when (next, previous, update, delete and add new buttons are presses)
- Finally it needs to be able to refresh and update in real time if an item is added or removed from the compiler
