Java绝美动态爱心代码

Java绝美动态爱心代码可以通过使用Java Swing编写实现。以下是一个简单的实现示例：

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

public class Heart extends JPanel implements Runnable {
    private double angle = 0;

    public void paintComponent(Graphics g) {
        super.paintComponent(g);

        Graphics2D g2d = (Graphics2D) g;
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

        int width = getWidth();
        int height = getHeight();

        double centerX = width / 2;
        double centerY = height / 2 - 55;

        double x, y, r;

        GeneralPath heart = new GeneralPath();

        r = 50 * Math.sin(angle);
        x = centerX + r * Math.cos(angle);
        y = centerY - r * Math.sin(angle);
        heart.moveTo(x, y);

        for (angle = 0; angle <= 2 * Math.PI; angle += 0.01) {
            r = 50 * Math.sin(angle);
            x = centerX + r * Math.cos(angle);
            y = centerY - r * Math.sin(angle);
            heart.lineTo(x, y);
        }

        heart.closePath();

        GradientPaint paint = new GradientPaint(0, 0, Color.RED, width, height, Color.PINK);
        g2d.setPaint(paint);

        g2d.fill(heart);

        angle += 0.01;
    }

    public void run() {
        try {
            while (true) {
                repaint();
                Thread.sleep(10);
            }
        } catch (InterruptedException ex) {
            System.out.println(ex);
        }
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Dynamic Heart");
        frame.add(new Heart());
        frame.setSize(300, 300);
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        Thread thread = new Thread(new Heart());
        thread.start();
    }
}

运行该程序，会显示一个动态的爱心图案，通过改变角度和颜色梯度，可以得到更加漂亮的效果。
