Java代码画一个爱心

这是Java画一个爱心的代码：

import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JFrame;
import javax.swing.JPanel;

@SuppressWarnings("serial")
public class HeartDrawing extends JPanel {

    // 定义窗口大小
    private static final int WIDTH = 600;
    private static final int HEIGHT = 600;

    private void drawHeart(Graphics g) {
        // 设置画笔颜色为红色
        g.setColor(Color.RED);

        // 计算心形曲线上的点坐标
        int x, y;
        double t;
        for (int i = -135; i <= 135; i++) {
            t = i * Math.PI / 45;
            x = (int) (16 * Math.sin(t) * Math.sin(t) * Math.sin(t)) + WIDTH / 2;
            y = (int) (-13 * Math.cos(t) + 5 * Math.cos(2 * t) + 2 * Math.cos(3 * t) + Math.cos(4 * t)) + HEIGHT / 2;
            g.fillOval(x, y, 5, 5);
        }
    }

    @Override
    public void paint(Graphics g) {
        super.paint(g);
        drawHeart(g);
    }

    public static void main(String[] args) {
        JFrame jFrame = new JFrame();
        jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        jFrame.setSize(WIDTH, HEIGHT);
        jFrame.add(new HeartDrawing());
        jFrame.setLocationRelativeTo(null);
        jFrame.setVisible(true);
    }
}
