有没有办法在使用super.paint(g)之后重新绘制图形？

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

public class MyPanel extends JPanel {
    
    public MyPanel() {
        super();
    }
    
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        // 绘制图形
        g.drawLine(50, 50, 200, 200);
    }
    
    public void redraw() {
        repaint();  // 重新绘制图形
    }
    
    public static void main(String[] args) {
        JFrame frame = new JFrame("Redraw Example");
        frame.setSize(300, 300);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        
        MyPanel panel = new MyPanel();
        frame.add(panel);
        frame.setVisible(true);
        
        // 延时2秒后重新绘制图形
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        
        panel.redraw();
    }
}
