The game of Black. Jack 21. Create a game of Black. Jack. 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 and Design 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 splits No insurance User 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 Black. Jack; a single player plays against the house for money. His bet is consistently $100. 00 and he starts with 1, 000. 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 11 points 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. blue are nouns (objects or fields)

Open Source and Standardization • Java. FX source code being contributed as part of Open. JFX http: //openjdk. java. net/projects/openjfx/ – Source code being contributed in phases – Initial phase: UI Controls • Oracle is committed to standardize Java. FX through JCP – One or more JSRs will be submitted – Expected to be become part of the Java SE specification

Distribution and Support • Java. FX Distribution – Java. FX Runtime can now be distributed with third party applications – Applies to Java. FX 2. 0. 2 and higher • Java. FX Platform Commercial Support – Java. FX is now part of the Java SE technologies covered through Oracle Premier Support – Applies to Java. FX 2. 0. 2 and higher

Let’s Compare: Java. FX 1. x import javafx. application. *; import javafx. scene. shape. *; import javafx. scene. paint. *; Stage { scene: Scene{ Content: [ Circle { center. X: 50 center. Y: 50 radius: 50 fill: Color. RED } ] } }

Let’s Compare: Java. FX 2. 0 public class Java. FXTest extends Application { @Override public void start(Stage stage) { Group root = new Group(); Scene scene = new Scene(root, 100); stage. set. Scene(scene); Circle c 1 = new Circle(50. 0 f, Color. RED); root. get. Children(). add(c 1); stage. set. Visible(true); } public static void main(String a[]) { Launcher. launch(Java. FXTest. class, null); } }

Let’s Compare: FXML <Border. Pane> <center> <Circle radius=“ 50” center. X=“ 50” center. Y=“ Let’s Compare: FXML

public class Java. FXTest extends Application { @Override public void start(Stage stage) { stage. set. Title(“FXML Example”); Parent root = FXMLLoader. load(get. Class(). get. Resource(“example. fxml"), Resource. Bundle. get. Bundle(“r. fxml_example")); stage. set. Scene(new Scene(root)); stage. show(); } }

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

Media • Java. FX supports both visual and audio media • Cross-platform Java. FX media file format (fxm, mp 3) – Platform specific formats supported via native players • Media class represents a media file • Media. Player provides control of the media rendering • Media. View uses Media. Player to render media as Node – Many Media. Views can use the same Media. Player (cheaply)

Adding HTML Content The Embedded Browser • Web. Engine – Provides basic web page browsing functionality – Supports user interaction: navigating links, submitting forms • Web. View – Web page as a Node in scenegraph • Effects can be applied – Encapsulates Web. Engine object – No plugin support

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 – Double. Property, String. Property, etc • Simple API – bind / unbind – bind. Bidirectional / unbind. Bidirectional – is. Bound

Simple Binding Example private Simple. Double. Property top. XProperty = new Simple. Double. Property(); private Simple. Double. Property top. YProperty = new Simple. Double. Property(); Line fold. Line = new Line(); fold. Line. set. End. X(200); fold. Line. set. End. Y(200); fold. Line. start. XProperty(). bind(top. XProperty); fold. Line. start. YProperty(). bind(top. YProperty); . . . top. XProperty. set(tx); top. YProperty. set(ty);

Timeline Based Animations • Timeline – Modifies values of variables specified in Key. Frames • Key. Frame: specifies that a variable should have – A particular value at a particular time • Key. Value: 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 Java. FX applications Other Java IDEs • Source editor with syntactic highlighting, code completion, refactoring etc. • Full debugger and Profiler support

Concurrency in java. FX 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. Future. Task class. The Task class enables developers to implement asynchronous tasks in Java. FX 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. 44 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.
