The game of BlackJack 21. Create a game of BlackJack. User plays against the computer which is the dealer.You must create a GUI application. This project provides an excellent opportunity to use your OO Analysis andDesign skills, as well as your Swing-GUI skills.

Here are the rules of blackjack: http://en.wikipedia.org/wiki/Blackjack

To keep things simple, you should use a 6-Deck shoe.No splitsNo insuranceUser starts with 1000$You must respect hard and soft aces (either 1 or 11)Dealer must hit on soft 17

There are many resource online where you can find png's or jpg's or cards.

Describe the system:

The game of BlackJack; a single player plays against the house for money. His bet is consistently $100.00 and he starts with 1,000.00. There is a shoe of six 52-card decks which is reshuffled when the shoe is half used. If the player wins the hand, his gets his bet back plus the amount of the bet. If he loses, he loses the money, and if he gets blackjack, he get's his bet * 1.5.

The player plays against a dealer who must follow the following strict rules; aces are worth 11points only, and the dealer must hit on 16 or below. The player however, is allowed to hit or hold on any hand-value. Furthermore, aces are worth either 1 or 11, whichever is more advantageous.

An initial two hands are dealt on seperate sides of a table consisting of two cards apiece. The dealer's hand displays only one card up. The player has the option to hit, hold, split, double-down, buy insurance, etc. For this initial version of the game, we'll consider only hit, hold, and deal.

• Applies to SWT applications as well

Swing and SWT Interop

• Faster loading of JavaFX Web applications based on Prism

• Pre-loader for improved user experience with JavaFX Web applications

Browser Plugin

Open Source and Standardization

• JavaFX source code being contributed as part of OpenJFXhttp://openjdk.java.net/projects/openjfx/– Source code being contributed in phases– Initial phase: UI Controls

• Oracle is committed to standardize JavaFX through JCP– One or more JSRs will be submitted– Expected to be become part of the Java SE specification

Distribution and Support

• JavaFX Distribution– JavaFX Runtime can now be distributed with third party

applications– Applies to JavaFX 2.0.2 and higher

• JavaFX Platform Commercial Support– JavaFX is now part of the Java SE technologies covered through

Oracle Premier Support– Applies to JavaFX 2.0.2 and higher

Let’s Compare: JavaFX 1.x

import javafx.application.*;import javafx.scene.shape.*;import javafx.scene.paint.*;

Stage { scene:Scene{ Content:[ Circle { centerX: 50 centerY: 50 radius: 50 fill: Color.RED } ] }}

Let’s Compare: JavaFX 2.0

public class JavaFXTest extends Application { @Override public void start(Stage stage) { Group root = new Group(); Scene scene = new Scene(root,100,100); stage.setScene(scene); Circle c1 = new Circle(50.0f, 50.0f, 50.0f, Color.RED); root.getChildren().add(c1); stage.setVisible(true); }

public static void main(String a[]) { Launcher.launch(JavaFXTest.class, null); } }

Let’s Compare: FXML

public class JavaFXTest extends Application { @Override public void start(Stage stage) { stage.setTitle(“FXML Example”); Parent root = FXMLLoader.load(getClass().getResource(“example.fxml"), ResourceBundle.getBundle(“r.fxml_example")); stage.setScene(new Scene(root)); stage.show();

Scene Graph

• Directed Acyclic Graph• Parents and children• Representation of the GUI components

• JavaFX supports both visual and audio media• Cross-platform JavaFX media file format (fxm, mp3)

– Platform specific formats supported via native players

• Media class represents a media file• MediaPlayer provides control of the media rendering• MediaView uses MediaPlayer to render media as Node

– Many MediaViews can use the same MediaPlayer (cheaply)

Adding HTML Content

• WebEngine– Provides basic web page browsing functionality– Supports user interaction: navigating links, submitting forms

• WebView– Web page as a Node in scenegraph

• Effects can be applied

– Encapsulates WebEngine object– No plugin support

rect.setRotate(45);

rect.setScaleX(2);rect.setScaleY(0.5);

Shear shear = new Shear(0.7, 0);rect.getTransforms().add(shear);

Binding

• Creates a dependency between a property and a changeable value

• High level API– Easy to use– Covers most common situations

• Low level API– Allows for more complex interactions– Optimised for fast execution and small footprint

Properties

• Basis for high level binding API• Concrete types for all primitives, String and Object

– DoubleProperty, StringProperty, etc

• Simple API– bind / unbind– bindBidirectional / unbindBidirectional– isBound

Simple Binding Example

private SimpleDoubleProperty topXProperty = new SimpleDoubleProperty();private SimpleDoubleProperty topYProperty = new SimpleDoubleProperty();

Line foldLine = new Line();foldLine.setEndX(200);foldLine.setEndY(200);foldLine.startXProperty().bind(topXProperty);foldLine.startYProperty().bind(topYProperty);

topXProperty.set(tx);topYProperty.set(ty);

Timeline Based Animations

• Timeline– Modifies values of variables specified in KeyFrames

• KeyFrame: specifies that a variable should have– A particular value at a particular time

• KeyValue: Value to be interpolated for an interval

Animated Transitions

• Pre-defined, single-purpose animations– Fade, Path, Pause, Rotate, Scale, Translate– Can specify to, from and by values

• Container transitions– Parallel, sequential– Can be nested arbitarily

• Transitions and Timelines share ancestary– A Timeline can be added to a Parallel / Sequential transition

Standard Java Tools for Easy Development

• Source editor with improved syntactic highlighting, code completion, refactoring etc.

• Full debugger and profiler support

• Project wizard for easy creation of JavaFX applications

Other Java IDEs• Source editor with syntactic highlighting,

code completion, refactoring etc.• Full debugger and Profiler support

JavaFX Scene Builder for Rapid UI Design

Binding one GUI component to anotherbtn.prefWidthProperty().bind(scene.widthProperty()); (TabsSample)

Binding GUI component to Worker (TimesControllerTask)lblStatus.textProperty().bind(getReviewsTask.messageProperty()); btnGo.disableProperty().bind(getReviewsTask.runningProperty()); lstView.itemsProperty().bind(getReviewsTask.valueProperty());

Define your own Thread-Safe properties and listen for changes (ThreadsController) service.getCounterProperty().addListener(new ChangeListener(){ @Override public void changed(ObservableValue o,Object oldVal, Object newVal){ System.out.println("Counter changed to: " + service.getCounter()); } });

Bindings

FXMLLoader loader = new FXMLLoader(getClass().getResource("/fxml/Threads.fxml")); Parent root = (Parent) loader.load(); ThreadsController controller = loader.getController(); controller.setStage(primaryStage);

In YourController, you need this method: public void setStage(Stage stage) { this.primaryStage = stage; }

Communicate between Main and Controller

The javafx.concurrent package consists of the Worker interface and two concrete implementations, Task and Service classes.

The Worker interface provides APIs that are useful for a background worker to communicate with the UI.

The Task class is a fully observable implementation of the java.util.concurrent.FutureTask class. The Task class enables developers to implement asynchronous tasks in JavaFX applications. The Task class defines a one-time object that cannot be reused.

The Service class executes tasks. If you need a reusable Worker object, use the Service class.

Concurrency in javaFX

Group effects and transforms to be applied to a collection of child nodes.Region class for nodes that can be styled with CSS and layout children.Control class for high-level skinnable nodes designed for user interaction.

Task Service

Worker(Interface)

Inside the call method, you can use:

updateProgress(), updateMessage() , updateTitle() methods, which update the values of the corresponding properties on the JavaFX Application thread.
