        setDefaultCloseOperation(EXIT_ON_CLOSE);
        setTitle("I am a duck!");
        add(new Hexas());
        setVisible(true);
    }

    public static void main(String[] args) {
        new HexagonWDW();
    }
}

    Image[] img;
    int xmax;
    int ymax;
    int totaloff;

        totaloff = 0;
        img = new Image[3];
        xs = new ArrayList();
        ys = new ArrayList();
        ims = new ArrayList();
        xmax = 2;
        ymax = 2;
        img[0] = new ImageIcon("img.png").getImage();
        img[1] = new ImageIcon("blue.png").getImage();
        img[2] = new ImageIcon("green.png").getImage();
    }

    public void paint(Graphics g) {
        super.paint(g);
        Graphics2D g2 = (Graphics2D) g;
        RenderingHints rh = new RenderingHints(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        rh.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
        g2.setRenderingHints(rh);
        init(g2);

    }

    public void init(Graphics2D g2) {
        int xr = 0;
        int yr = 0;
        setBackground(Color.white);
        Dimension size = getSize();
        double w = size.getWidth();
        double h = size.getHeight();
        int r = 20;
        double pi = Math.PI;
        int q = 1;
        for (int j = 0; j < ymax; j++) {
            System.out.println("Y: " + j);
            q = q == 1 ? 0 : 1;
            totaloff += q;
            int aq = q == 1 ? 0 : 1;
            int y = 50 + j * 20;
            for (int a = 0; a < (q + xmax); a++) {
                Polygon sprite = new Polygon();
                int x = 50 + a * 65 + aq * 32;
                System.out.println("Totaloff: " + totaloff + " and q: " + q);
                System.out.println("Poly: " + (int) j * xmax + totaloff + a + q + "\n");
                for (int i = 0; i < 6; i++) {
                    xr = (int) (x + r * Math.cos(i * 2 * pi / 6));
                    yr = (int) (y + r * Math.sin(i * 2 * pi / 6));
                    xs.add(j * xmax + totaloff + a + q, xr);
                    ys.add(j * xmax + totaloff + a + q, yr);
                    ims.add(j * xmax + totaloff + a + q, 0);
                    sprite.addPoint(xr, yr);
                    System.out.println("Point added at" + i + xr + yr);
                }
                g2.setColor(Color.black);
                g2.fillPolygon(sprite);
                g2.setColor(Color.blue);
                g2.drawPolygon(sprite);
                int cur = ims.get(j * ymax + totaloff + a + q);
                g2.drawImage(img[cur], xr - 15, yr + 15, null);
            }
        }
    }

    public void updateIcons(Graphics g2) {
        for (int i = 0; i < (xmax * ymax + totaloff); i++) {
            g2.drawImage(img[ims.get(1)], xs.get(1) - 15, ys.get(1) + 15, null);
        }
    }
}

作为多边形输出的内容应该是每个多边形的索引，从0开始，每次递增1，但显然不是。

我能做的任何事情都可以使循环运行得更准确，我的数字达到它们应该达到的水平。我确信您不会编写左对齐的代码，所以不要期望我们阅读左对齐的代码。编辑您的问题并修复代码的格式。您不应该覆盖框架的paint（）方法来进行自定义绘制。阅读上的Swing教程了解正确的方法。缓存生成

多边形的结果

，并在每次调用

paintComponent

时对其进行简单的重画…1）在调试输出中添加空格，以便我们可以判断哪些数字属于哪个变量2）请注释/使用更详细的变量名，以便更容易地了解你想做什么。
