Java 可视化形状绘制工具 - 使用坐标点绘制多边形和圆弧

以下是使用Java编写的程序，可以按照给定的坐标顺序绘制多个可视化形状，并将它们绘制到一个窗口中。

public class ShapeVisualization extends JFrame {

    private List<String> shapes;

    public ShapeVisualization(List<String> shapes) {
        this.shapes = shapes;
        setTitle('Shape Visualization');
        setSize(800, 600);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);
        setVisible(true);
    }

    @Override
    public void paint(Graphics g) {
        super.paint(g);
        for (String shape : shapes) {
            drawShape(g, shape);
        }
    }

    private void drawShape(Graphics g, String shape) {
        String[] coordinates = shape.split(';');
        for (int i = 0; i < coordinates.length - 1; i++) {
            String currentCoordinate = coordinates[i];
            String nextCoordinate = coordinates[i + 1];
            if (currentCoordinate.startsWith('(') && currentCoordinate.endsWith(')')) {
                // Draw arc
                String[] arcCoordinates = currentCoordinate.substring(1, currentCoordinate.length() - 1).split(',');
                double x1 = Double.parseDouble(arcCoordinates[0].trim());
                double y1 = Double.parseDouble(arcCoordinates[1].trim());
                double x2 = Double.parseDouble(arcCoordinates[2].trim());

                int y1Int = (int) (y1 * 100);
                int x2Int = (int) (x2 * 100);
                int y2Int = (int) (y2 * 100);
                int x3Int = (int) (x3 * 100);
                int y3Int = (int) (y3 * 100);

                if (clockwise) {
                    g.drawArc(x1Int, y1Int, x2Int, y2Int, x3Int, y3Int);
                } else {
                    g.drawArc(x1Int, y1Int, x2Int, y2Int, x3Int, -y3Int);
                }
            } else {
                // Draw line
                String[] currentCoordinates = currentCoordinate.split(',');
                String[] nextCoordinates = nextCoordinate.split(',');
                double x1 = Double.parseDouble(currentCoordinates[0].trim());
                double y1 = Double.parseDouble(currentCoordinates[1].trim());
                double x2 = Double.parseDouble(nextCoordinates[0].trim());
                double y2 = Double.parseDouble(nextCoordinates[1].trim());

                int x1Int = (int) (x1 * 100);
                int y1Int = (int) (y1 * 100);
                int x2Int = (int) (x2 * 100);
                int y2Int = (int) (y2 * 100);

                g.drawLine(x1Int, y1Int, x2Int, y2Int);
            }
        }
    }

    public static void main(String[] args) {
        List<String> shapes = new ArrayList<>(Arrays.asList(
                '0.000,6.000;0.000,0.000;32.639,0.000;32.639,6.069;0.000,10.069;(0.000,10.069;0.000,6.000;103.105,2.328;true);',
                '0.000,6.000;0.000,0.000;32.639,0.000;32.639,6.069;0.000,10.069;(0.000,10.069;0.000,6.000;103.105,2.328;true);'
        ));

        SwingUtilities.invokeLater(() -> new ShapeVisualization(shapes));
    }
}

注意：由于该程序使用了Swing库进行图形绘制，因此建议在图形界面的主线程中运行该程序。上述代码的main方法已经做了相应的处理。
