1) The tutorial code contains three different Pane classes that represent three different views of a DVDCollection. These classes are called DVDCollectionAppView1, DVDCollectionAppView2, and DVDCollectionAppView3. These three views are shown below: Title, Year, Length (min DVDs Tite Length Title Length Delete Delele Stats Add Stats 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. Run the DVDCollectionApp1 class and ensure that the window contains the first view above. Change the line that creates the view to create a DVDCollectionAppView2 view instead of a DVDCollectionAppView1 view. Re-run the code and ensure that it looks like the 2nd view above. Change it one more time to a DVDCollection AppView3 view and make sure that it looks like the third view. 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
