能否提供一份Java实现的烟花秀源代码示例？

当然可以，以下是一个简单的Java Swing程序，它模拟了烟花秀的效果。这个例子使用了Java的图形用户界面（GUI）API来绘制不同形状和颜色的"烟花"。请注意，这只是一个基础示例，并非完整的烟花秀游戏，但它能展示一些基本的概念：

import javax.swing.*;
import java.awt.*;
import java.awt.geom.Path2D;
import java.util.Random;

public class Fireworks extends JFrame {
    private static final int CANVAS_WIDTH = 800;
    private static final int CANVAS_HEIGHT = 600;
    private Random random;

    public Fireworks() {
        setTitle("简单烟花秀");
        setSize(CANVAS_WIDTH, CANVAS_HEIGHT);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setResizable(false);
        setLocationRelativeTo(null);

        random = new Random();

        createCanvas();
    }

    private void createCanvas() {
        JPanel canvasPanel = new JPanel() {
            @Override
            protected void paintComponent(Graphics g) {
                super.paintComponent(g);
                Graphics2D g2d = (Graphics2D) g;

                // 创建随机的烟花效果
                for (int i = 0; i < 50; i++) {
                    double x = random.nextDouble() * CANVAS_WIDTH;
                    double y = random.nextDouble() * CANVAS_HEIGHT;
                    double size = random.nextDouble() * 20 + 10;
                    Color color = new Color(random.nextInt(256), random.nextInt(256), random.nextInt(256));

                    Path2D.Float path = new Path2D.Float(Path2D.WIND_EVEN_ODD);
                    path.moveTo(x, y);
                    path.arcTo(x + size, y, size, size, -45, 90);
                    g2d.setPaint(color);
                    g2d.fill(path);
                }
            }
        };

        add(canvasPanel);
        setVisible(true);
    }

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