Keep using your project from the last assignment and 1. add View.java, MainFrame.Java and InitialPanel.java from this A04A starter project or 1. Use the A04A starter project and 1. add the updates from your previous project (mostly from Model.java) The starter NetBeans project that you will use looks like this:

The students are created in Model. Controller will retrieve the data from Model and pass it to View.View will use buttons organized in a layout to display the following result: A04A - Basic Graphics NAME - Emily Smith Age = 20, address=107 W College Avenue, State College, PA,16801 13 NAME - Mary Doe Age = 20, address=200 W College Avenue,State College, PA, 16801 9 NAME = John Doe Age = 20, address=300 W College Avenue,State College, PA,16801 10 The number of credits are calculated on the fly in Model and might vary in the output of your assignment. You will need to work on View adding single statements and methods to achieve the lab objectives. Model and Controller might need few updates to adjust on how View wants to receive the Strings with the information to be displayed. App o it has the main method which is the method that Java looks for and runs to start any application o it creates 3 objects, one of the Model class, one of the View class and one of the Controller class. o When it creates Controller, it passes the two other objects as input parameters so that Controller has access to Model and View. Model model = new Model(); View view = new View(); Controller controller = new Controller (model, view); Controller o will retrieve from Model (using the model object) data about each student to be displayed o will pass the data to View, which will display it o the two operations above will work best if Model and View have methods that help with that.
