Question

我正在编写一个模拟单轮纸牌游戏WAR的程序。

我不知道如何以图形方式显示卡片（数字/颜色/套装）。

// Class Definition
class Project4 {

    // Main method definition
    public static void main(String[] args) {

            // Object and Variable Declarations 
            JFrame win;
            Container contentPane;
            Graphics g;
            String player1Name, player2Name, scoreWinLoss;
            //This is the graphics portion, all of the graphics (so far) are working.
            win = new JFrame("War Game");
            win.setSize(900, 600);
            win.setLocation(100, 100);
            win.setVisible(true);
            win.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

            Color white = new Color(255, 255, 255);
            Color white2 = new Color(255, 255, 255);
            Color black = new Color(0, 0, 0);
            Color black2 = new Color(0, 0, 0);

            contentPane = win.getContentPane();
            //Also if anyone knows how to change this .setBackground(Color.Green)from lime green to forest(card table) green that would be awesome!

            contentPane.setBackground(Color.GREEN);

            g = contentPane.getGraphics();
            Font font = new Font("Serif", Font.BOLD, 25);
            g.setFont(font);

            try {
                Thread.sleep(200);
            } catch (Exception e) {}

            player1Name = JOptionPane.showInputDialog(null, "Player 1, what is your name?");
            player2Name = JOptionPane.showInputDialog(null, "Player 2, what is your name?");
            g.setColor(black);
            g.drawString(player1Name, 220, 35);
            g.setColor(black2);
            g.drawString(player2Name, 625, 35);

            g.setColor(white);
            g.fillRoundRect(125, 50, 250, 450, 20, 20);
            g.setColor(white2);
            g.fillRoundRect(525, 50, 250, 450, 20, 20);
            g.setColor(black);
            g.drawRoundRect(125, 50, 250, 450, 20, 20);
            g.setColor(black2);
            g.drawRoundRect(525, 50, 250, 450, 20, 20);

            //This is where it gets confusing and this stuff is all not working

            int card1Max = 14, card1Min = 2, card2Max = 14, card2Min = 2, randomNum1 = 0, randomNum2 = 0;

            g.setColor(black);
            g.drawInt(randomNum1, 150, 35);
            g.setColor(black2);
            g.drawInt(randomNum2, 500, 35);

            Random randomPicker = new Random(System.currentTimeMillis());
            randomNum1 = randomPicker.nextInt(card1Max - card1Min + 1) + card1Min;
            randomNum2 = randomPicker.nextInt(card2Max - card2Min + 1) + card2Min;

            if (randomNum1 < randomNum2) {
                scoreWinLoss = player2Name + " won!";
            } else if (randomNum1 > randomNum2) {
                scoreWinLoss = player1Name + " won!";
            } else if (randomNum1 == randomNum2) {
                scoreWinLoss = "It's a tie! Play again to determine a winner.";
            }

Answer 1

不要像你一样玩图形对象：

   g.setColor(black);
   g.drawString(player1Name, 220, 35);

这很糟糕！

相反，你应该看一下布局。查看 GridLayout 或 GridBagLayout 。这些允许您将JPanels组织为网格。使用这些面板，您可以设置背景颜色并添加文本（通过JLabel）。

Answer 2

如果我理解您的问题：以简单的方式，您可以将JPanel与CardLayout一起使用，然后通过JLabel.setImageIcon(ImageIcon imageIcon) JLabel方法设置来自网络的卡片图片这张照片和CardLayout上的照片会带来卡片。

用Java显示卡片
