通过Java 画一个太极图

以下是Java代码实现太极图的过程：

import java.awt.*;
import java.awt.geom.*;

public class TaiChi extends Frame {
    private static final long serialVersionUID = 1L;

    public TaiChi() {
        super("太极图");
        setSize(400, 400);
        setBackground(Color.white);
        setVisible(true);
    }

    public void paint(Graphics g) {
        Graphics2D g2 = (Graphics2D) g;
        g2.translate(200, 200);

        // 画圆
        Ellipse2D.Double circle = new Ellipse2D.Double(-100, -100, 200, 200);
        g2.draw(circle);

        // 画两个半圆
        Arc2D.Double arc1 = new Arc2D.Double(-100, -100, 200, 200, 90, 180, Arc2D.OPEN);
        Arc2D.Double arc2 = new Arc2D.Double(-100, -100, 200, 200, -90, 180, Arc2D.OPEN);
        g2.draw(arc1);
        g2.draw(arc2);

        // 画两个小圆
        g2.setPaint(Color.white);
        Ellipse2D.Double smallCircle1 = new Ellipse2D.Double(-50, -50, 50, 50);
        Ellipse2D.Double smallCircle2 = new Ellipse2D.Double(0, -50, 50, 50);
        g2.fill(smallCircle1);
        g2.setPaint(Color.black);
        g2.fill(smallCircle2);

        // 画两个小点
        g2.setPaint(Color.white);
        Ellipse2D.Double smallPoint1 = new Ellipse2D.Double(-25, -25, 5, 5);
        Ellipse2D.Double smallPoint2 = new Ellipse2D.Double(20, -25, 5, 5);
        g2.fill(smallPoint1);
        g2.setPaint(Color.black);
        g2.fill(smallPoint2);
    }

    public static void main(String[] args) {
        TaiChi tc = new TaiChi();
    }
}

运行代码后，会弹出一个窗口，展示出太极图。
