  The tutorial code contains two different Pane classes that represent three different views of a DVDCollection These classes are called DVDCollectionAppView1 and DVDCollectionAppView2 DVDs Title Length Title Add Delete Stats Year Length Add Stats DVDCollectionAppView1 DVDCollectionAppView2 There is also an application called DVDCollectionApp1 which is used as the controller for the application. That is, it represents the main application onto which the view is attached A. Run the DVDCollectionApp1 class and ensure that the window contains the first view above B. Change the line that creates the view to create a DVDCollectionAppView2 view instead of a DVDCollectionAppView1 view C. Re-run the code and ensure that it looks like the 2nd view above Note that we will keep changing which view we have in the application throughout the tutorial D. Rewrite the line so that it creates a DVDCollectionAppView1 view again. Notice how we can simply swap various views in and out of our application with this simple one- line change. This is one advantage of separating the view from the controller in our MVC strategy Z) Now we will insert the model into the mix as our third part of the MVC. The model is a DVDCollection object
