Java爱心烟花特效代码

在Java中创建爱心烟花特效的代码通常涉及到图形绘制、动画以及随机数生成等部分。下面是一个简单的示例，使用Swing库来画出爱心形状并在每次循环中改变位置：

import javax.swing.*;
import java.awt.*;
import java.awt.geom.Arc2D;
import java.util.Random;

public class HeartFireworks extends JFrame {
    private int x = 50;
    private int y = 50;
    private Random random = new Random();
    private Color color;

    public HeartFireworks() {
        setSize(400, 400);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(null);

        // 创建爱心形状
        Graphics2D g = createGraphics();
        g.setColor(Color.WHITE);
        g.setStroke(new BasicStroke(2));
        g.draw(new Arc2D.Float(x, y, 70, 70, -180, 90, Arc2D.OPEN));

        startAnimation();
    }

    private void startAnimation() {
        Timer timer = new Timer(50, e -> {
            x += random.nextInt(10) - 5; // 随机移动X轴
            y += random.nextInt(10) - 5; // 随机移动Y轴

            if (x > getWidth() || x < 0 || y > getHeight() || y < 0) {
                stopAnimation(); // 当超出边界时停止动画
                return;
            }

            repaint(); // 刷新屏幕更新爱心的位置
        });

        timer.start();
    }

    private void stopAnimation() {
        ((TimerTask) SwingUtilities.invokeLater(() -> timer.stop())).cancel();
    }

    @Override
    protected void paint(Graphics g) {
        super.paint(g);
        g.setColor(color);
        g.setStroke(new BasicStroke(2));
        g.draw(new Arc2D.Float(x, y, 70, 70, -180, 90, Arc2D.OPEN));
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(() -> {
            HeartFireworks window = new HeartFireworks();
            window.setVisible(true);
        });
    }
}
