Here is some code that you can use as a template:

 import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.layout.Pane; import javafx.stage.Stage; public class DVDCollectionApp extends Application { public void start(Stage primaryStage) { Pane aPane = new Pane(); // Create the labels  // ... ADD CODE HERE ... //  // Create the lists  String[] titles = {"Star Wars", "Java is cool", "Mary Poppins", "The Green Mile"}; String[] years = {"1978", "2002", "1968", "1999"}; String[] lengths = {"124", "93", "126", "148"}; // ... ADD CODE HERE ... //  // Create the buttons. The following code shows how to set the font,  // background color and text color of a button:  // b.setStyle("-fx-font: 12 arial; -fx-base: rgb(0,100,0); " +  // "-fx-text-fill: rgb(255,255,255);");  // ... ADD CODE HERE ... //  // Dont forget to add the components to the window, set the title,  // make it non-resizable, set Scene dimensions and then show the stage  // ... ADD CODE HERE ... //  } public static void main(String[] args) { launch(args); } } 

Now we will also use the newly created Pane in another interface. Create a class callled DVDCollectionApp2 to represent the GUI shown on the next page, which is similar, but has only one ListView (which is a list of DVDs now, instead of Strings) and contains three TextField objects. Here is some code that you can use to get you started:

 import javafx.application.Application; import javafx.collections.FXCollections; import javafx.scene.Scene; import javafx.scene.control.Label; import javafx.scene.control.ListView; import javafx.scene.control.TextField; import javafx.scene.layout.Pane; import javafx.stage.Stage; public class DVDCollectionApp2 extends Application { public void start(Stage primaryStage) { Pane aPane = new Pane(); // Create the labels  Label label1 = new Label("DVDs"); Label label2 = new Label("Title"); Label label3 = new Label("Year"); Label label4 = new Label("Length"); // Create the TextFields  TextField tField = new TextField(); TextField yField = new TextField(); TextField lField = new TextField(); // Create the lists  ListView tList = new ListView(); // Create the buttons  DVDButtonPane buttonPane = new DVDButtonPane(); // Add all the components to the window  aPane.getChildren().addAll(label1, label2, label3, label4, tField, yField, lField, tList, buttonPane); primaryStage.setTitle("My DVD Collection"); primaryStage.setResizable(false); primaryStage.setScene(new Scene(aPane, 548,268)); primaryStage.show(); } public static void main(String[] args) { launch(args); } } 

We will now make adjustments to the code to populate the interface with a DVDCollection object as its model. In the DVDCollectionApp2 class, add an attribute to store the model as follows:

private DVDCollection model;

Then create the following constructor, which will set that attribute to be the example DVDCollection that was defined in that model class:

public DVDCollectionApp2() { model = DVDCollection.example1(); } 

Recall that we used the setItems() method to add some items to a ListView:

ListView yList = new ListView(); String[] years = {"1978", "2002", "1968", "1999"}; yList.setItems(FXCollections.observableArrayList(years)); 

Modify your code so that the tList ListView contains the list of DVD objects that are contained in the DVDCollection model. Here is what you should see:

public class DVD implements Comparable { private String title; private int year; private int duration; public DVD () { this ("",0,0); } public DVD (String newTitle, int y, int minutes) { title = newTitle; year = y; duration = minutes; } public int compareTo(Object obj) { if (obj instanceof DVD) { DVD aDVD = (DVD)obj; return title.compareTo(aDVD.title); } return 0; } public String getTitle() { return title; } public int getDuration() { return duration; } public int getYear() { return year; } public void setTitle(String t) { title = t; } public void setDuration(int d) { duration = d; } public void setYear(int y) { year = y; } public String toString() { return ("DVD (" + year + "): \"" + title + "\" with length: " + duration + " minutes"); } public static void main(String args[]) { System.out.println(DVD.parseFrom("Rush Hour 2,2001,118")); } } 

public class DVDCollection { public static final int MAX_DVDS = 100; private DVD[] dvds; private int dvdCount; public DVDCollection() { dvds = new DVD[MAX_DVDS]; } public DVD[] getDvds() { return dvds; } public int getDvdCount() { return dvdCount; } public String toString() { return ("DVD Collection of size " + dvdCount); } public void add(DVD aDvd) { if (dvdCount MAX_DVDS) dvds[dvdCount++] = aDvd; } public boolean remove(String title) { for (int i=0; idvdCount; i++) { DVD d = dvds[i]; if (dvds[i].getTitle().equals(title)) { dvds[i] = dvds[dvdCount-1]; dvdCount--; return true; } } return false; } public static DVDCollection example1() { DVDCollection c = new DVDCollection(); c.add(new DVD("If I Was a Student", 2007, 65)); c.add(new DVD("Don't Eat Your Pencil !", 1984, 112)); c.add(new DVD("The Exam", 2001, 180)); c.add(new DVD("Tutorial Thoughts", 2003, 128)); c.add(new DVD("Fried Monitors", 1999, 94)); return c; } } 

import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.layout.Pane; import javafx.stage.Stage; public class DVDCollectionApp extends Application { public void start(Stage primaryStage) { Pane aPane = new Pane(); // Create the labels  // ... ADD CODE HERE ... //   // Create the lists  String[] titles = {"Star Wars", "Java is cool", "Mary Poppins", "The Green Mile"}; String[] years = {"1978", "2002", "1968", "1999"}; String[] lengths = {"124", "93", "126", "148"}; // ...

ADD CODE HERE ... //  } public static void main(String[] args) { launch(args); } } 

import javafx.scene.layout.Pane; public class DVDButtonPane extends Pane { // Replace this with your own code } 

import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Label; import javafx.scene.control.ListView; import javafx.scene.control.TextField; import javafx.scene.layout.Pane; import javafx.stage.Stage; public class DVDCollectionApp2 extends Application { public void start(Stage primaryStage) { Pane aPane = new Pane(); // Create the labels  Label label1 = new Label("DVDs"); Label label2 = new Label("Title"); Label label3 = new Label("Year"); Label label4 = new Label("Length"); // Create the TextFields  TextField tField = new TextField(); TextField yField = new TextField(); TextField lField = new TextField(); // Create the lists  ListView tList = new ListView(); // Create the buttons  DVDButtonPane buttonPane = new DVDButtonPane(); // Add all the components to the window  aPane.getChildren().addAll(label1, label2, label3, label4, tField, yField, lField, tList, buttonPane); primaryStage.setTitle("My DVD Collection"); primaryStage.setResizable(false); primaryStage.setScene(new Scene(aPane, 548,268)); primaryStage.show(); } public static void main(String[] args) { launch(args); } } 

Create a class called DVDCollectionApp which will represent the graphical user interface (i.e., GUI) for a DVDCollection object. The GUI will have the following components laid out manually (i.e., a Layout should NOT be used): three Label objects, 3 ListView objects and 3 Button objects as shown below. In this example, the ListView components have widths of 200, 60 and 60, respectively and they all have a height of 150. The Add, Delete and Stats buttons have widths of 95, 95 and 60, respectively and all three have a height of 30. The buttons use 12pt Arial font. The margin around the window and between components is 10. The window is non-resizable and the overall window dimensions are 249 x 228 My DVD Collection Title Length 124 93 126 148 Year Star Wars Java is cool Mary Poppins The Green Mile 1978 2002 1968 1999 Add Delete Stats
