App creates Model and View objects. Then it creates a Controller object passing the model and view objects as input parameters to controller The Controller package has the Controller class. Controller has access to model and view and is in charge of bringing data from Model and sending it to view. Projects Files Services L01 MVC Source Packages D

Lebanon, Pa., highSchool-Mount Lebanon .name=Matthew Baney, weight-225. hometown=State College, Pa., highSchool-State College using the no-parameter constructor Functionality The main objective is to make View display the information about the 5 Person objects. These 5 objects are created in Model in the method loadData(). Controller will retrieve the data from Model using the method String getData(int n) and pass it to View.View will use the method void basicDisplay(String s) to display data from each object with the following result Person{name-Marcus Allen, weight-200, hometown Upper Marlboro, Md., highschool-Dr. Henry A.

The classes App 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. When it creates Controller, it passes the two other objects as input parameters so that Controller has access to Model and View. model - new Modelo: View view = new View: Controller controller = new Controller(model, view) Controller o will retrieve data from Model using the model object to call the method String getData(int n) . n = 1 will return the first Person, n=2 the second Person and so on. after calling all thels objects, Controller will try to call a 6th object and should get a string with a error message. o will pass the data from each person at a time to View, which will display it the two operations above will work best if Model and View have methods that help with that You are writing these methods o For instance, controller might look like this: Controller o will retrieve data from Model using the model object to call the method String getData(int n) . n - 1 will return the first Person, n =2 the second Person and so on. . after calling all the 5 objects, Controller will try to call a 6th object and should get a string with a error message. o will pass the data from each person at a time to View, which will display it the two operations above will work best if Model and View have methods that help with that. You are writing these methods For instance, controller might look like this: view.basicDisplayCmodel.getData(1)); view.basicDisplay(model getData(2)); view.basicDisplay(model.getData(6): Model o it is already given in the starter project although you will need to add some functionality o it needs a method, loadData(), to load the data, i.e., initialize the 5 Person objects o it needs a method, String getData(int n), which returns data about a specific Person (you will write this method or a similar one) it returns the result of toString for a Person object (from 1 to 5) any other value of n should return the message "invalid input parameter" View In this assignment, it is a very simple class (it will get more complex quickly in the next two assignments) it needs a method, loadData), to load the data, i.e. Initialize the 5 Person objects o it needs a method, String getData(int n), which returns data about a specific Person you will write this method or a similar one) it returns the result of toString for a Person object (from 1 to 5) any other value of n should return the message "invalid input parameter View In this assignment, it is a very simple class (it will get more complex quickly in the next two assignments) o it just needs to display the text data that it will receive from Controller It needs a method, vold basicDisplay (Strings) to do this Person o it is the same as the last assignment, no changes Output The output will look like this: Person[name-Marcus Allen, weight-200, hometownupper Marlboro, Md., highschool-Dr. Henry A.
