Java编程：从黑杰克游戏到图形用户界面开发

1. 黑杰克游戏实现

黑杰克（BlackJack）是一款经典的纸牌游戏，我们可以使用Java语言来实现它。以下是黑杰克游戏的Java代码实现：

/*
* BlackJack
* A simple BlackJack card game simulation
*/
import java.util.Vector;
import java.io.*;
public class BlackJack {
    protected RandomCardDeck deck;
    protected Vector dealerHand, playerHand;
    protected int dealerPoints, playerPoints;
    protected final static char HIT = 'H', STAND = 'S';

    public BlackJack() {
        Card card;
        dealerHand = new Vector();
        playerHand = new Vector();
        deck = new RandomCardDeck();
        for (int c = 0; c < deck.getNumCards(); c++) {
            card = deck.getCard(c);
            if (card.isPictureCard()) {
                card.setValue(10);
