java写一个带特效的爱心

很高兴回答您的问题！以下是一个使用 Java 编写的带特效的爱心：

import java.awt.*;
import javax.swing.*;

public class HeartAnimation extends JPanel implements Runnable {
    private int x, y;
    private int size;
    private int angle;
    private int delay;

    public HeartAnimation(int x, int y, int size, int angle, int delay) {
        this.x = x;
        this.y = y;
        this.size = size;
        this.angle = angle;
        this.delay = delay;
    }

    @Override
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        g2d.translate(x, y);
        g2d.rotate(Math.toRadians(angle));
        g2d.scale(size, size);
        g2d.setColor(Color.RED);
        g2d.fillOval(-10, -10, 20, 20);
        g2d.fillOval(0, -10, 20, 20);
        g2d.fillPolygon(new int[] {-10, 0, 10}, new int[] {0, 20, 0}, 3);
        g2d.rotate(Math.toRadians(-angle));
        g2d.translate(-x, -y);
    }

    @Override
    public void run() {
        try {
            while (true) {
                angle += 5;
                size += 0.01;
                x += 2 * Math.sin(Math.toRadians(angle));
                y += 2 * Math.cos(Math.toRadians(angle));
                Thread.sleep(delay);
                repaint();
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Heart Animation");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 400);
        HeartAnimation heart = new HeartAnimation(200, 200, 1, 0, 10);
        frame.add(heart);
        frame.setVisible(true);
        new Thread(heart).start();
    }
}

这个程序使用 Java Swing 绘制一个带特效的爱心，可以在窗口中移动和旋转。您可以在 main 方法中修改 x、y、size、angle 和 delay 参数来调整爱心的位置、大小、旋转速度和动画延迟。希望这个程序能够帮助到您！
