My code for a drawing will open the JFrame, but not show what I drew

So I’m trying to make a drawing for an assignment that includes different shapes. I have the code for the drawing the and the window, but when I run it the only thing that shows up is the JFrame and not the drawing I am trying to display, which in this case is a snowman.

MyFrame.Java This is my code for the drawing and JFrame

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

public class MyFrame extends Main {

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

    // Draw the body of the snowman
    g.setColor(Color.WHITE);
    g.fillOval(200, 50, 200, 200);
    g.fillOval(150, 150, 300, 300);
    g.fillOval(100, 300, 400, 400);

    // Draw the buttons
    g.setColor(Color.BLACK);
    g.fillOval(250, 250, 50, 50);
    g.fillOval(350, 250, 50, 50);
    g.fillOval(300, 350, 50, 50);

    // Draw the eyes and mouth
    g.fillOval(250, 200, 20, 20);
    g.fillOval(350, 200, 20, 20);
    g.drawArc(300, 250, 100, 50, 200, 140);

    // Draw the arms
    g.drawLine(150, 200, 75, 100);
    g.drawLine(450, 200, 525, 100);

    // Draw the hat
    g.setColor(Color.BLACK);
    g.fillRect(250, 75, 100, 25);
    g.fillRect(275, 25, 50, 50);
}

public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.setTitle("Snowman");
    frame.setSize(700, 700);
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setVisible(true);
}

}

Main.Java This is my other class.

import java.awt.Graphics;

public class Main {

public static void main(String[] args) {
    
    new MyFrame();

}

public void paintComponent(Graphics g) {
    // TODO Auto-generated method stub
    
}

}
