java烟花代码动态网页

以下是一个使用Java编写的烟花特效的动态网页代码示例：

import javax.swing.*;
import java.awt.*;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.util.ArrayList;
import java.util.List;

public class FireworksWebPage extends JFrame {
    private List<Firework> fireworks;

    public FireworksWebPage() {
        setTitle("烟花特效");
        setSize(800, 600);
        setLocationRelativeTo(null);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        fireworks = new ArrayList<>();

        FireworksPanel panel = new FireworksPanel();
        panel.addMouseListener(new MouseAdapter() {
            @Override
            public void mouseClicked(MouseEvent e) {
                fireworks.add(new Firework(e.getX(), e.getY()));
            }
        });

        add(panel);
        setVisible(true);

        animate();
    }

    private void animate() {
        while (true) {
            for (Firework firework : fireworks) {
                firework.update();
            }
            repaint();

            try {
                Thread.sleep(10);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    private class FireworksPanel extends JPanel {
        @Override

            super.paintComponent(g);
            for (Firework firework : fireworks) {
                firework.draw(g);
            }
        }
    }

            this.x = x;
            this.y = y;
            this.size = 5;
            this.color = new Color((int) (Math.random() * 256), (int) (Math.random() * 256), (int) (Math.random() * 256));
            this.speed = (int) (Math.random() * 5) + 1;
        }

        public void update() {
            y -= speed;
            size += 1;
            if (size >= 50) {
                fireworks.remove(this);
            }
        }

        public void draw(Graphics g) {
            g.setColor(color);
            g.fillOval(x - size / 2, y - size / 2, size, size);
        }
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(FireworksWebPage::new);
    }
}
