请用Java实现心形函数图像

以下是Java实现心形函数图像的代码：

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

public class HeartFunction extends JPanel {
    private static final long serialVersionUID = 1L;
    private static final int WIDTH = 600;
    private static final int HEIGHT = 600;
    private static final int SCALE = 10;

    public HeartFunction() {
        setPreferredSize(new java.awt.Dimension(WIDTH, HEIGHT));
    }

    @Override
    public void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.setColor(Color.RED);
        for (double t = -Math.PI; t <= Math.PI; t += 0.01) {
            double x = 16 * Math.pow(Math.sin(t), 3);
            double y = 13 * Math.cos(t) - 5 * Math.cos(2 * t) - 2 * Math.cos(3 * t) - Math.cos(4 * t);
            int xScaled = (int) (x * SCALE + WIDTH / 2);
            int yScaled = (int) (y * SCALE + HEIGHT / 2);
            g.drawLine(xScaled, yScaled, xScaled, yScaled);
        }
    }

    public static void main(String[] args) {
        JFrame frame = new JFrame("Heart Function");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setContentPane(new HeartFunction());
        frame.pack();
        frame.setVisible(true);
    }
}

你可以运行这个程序来看到心形函数的图像。
