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)

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=“ 50”/> </center> </Border. Pane> 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(); } }

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

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. 43 Copyright © 2011, Oracle and/or its affiliates. All rights reserved.
