I am trying to add one rectangle into another container rectangle

Question

However, only the container shows up. Here is my code:
Rectangle.java
/** Rectangle Supplier Class
* Author: David D. Riley modified by Deborah WHitfield
* Date: April, 2004
public class Rectangle extends JComponent {
     private static final long serialVersionUID = 1L;
     /** post: getX() == x and getY() == y
* and getWidth() == w and getHeight() == h
* and getBackground() == Color.black
     public Rectangle(int x, int y, int w, int h) {
super();
          setBounds(x, y, w, h);
setBackground(Color.black);
/** post: this method draws a filled Rectangle
* and the upper left corner is (getX(), getY())
* and the rectangle's dimensions are getWidth() and getHeight()
* and the rectangle's color is getBackground()
public void paint(Graphics g) {
g.setColor( getBackground() );
g.fillRect(0, 0, getWidth()-1, getHeight()-1);
repaint();
// paintChildren(g);
digit.java
import javax.swing.JFrame;
import java.awt.Color;
public class digit {
     private Rectangle topLeft, top, topRight, mid, bottomLeft, bottom, bottomRight, container;
     public digit(JFrame window, int x, int y) {
          container = new Rectangle(x, y, 125, 175);
          container.setBackground(Color.white);
          container.setVisible(true);
          topLeft = new Rectangle(0, 0, 50, 50);
          topLeft.setBackground(Color.red);
          container.add(topLeft,0);
          window.add(container,0);
lastly, Driver.java
import java.awt.Color;
import javax.swing.JFrame;
public class Driver {
     private JFrame window;
     public static void main(String [] args){
          JFrame window = new JFrame ("Window");
          window.setBounds(30, 100, 800, 800);
          window.setVisible(true);
          digit d1 = new digit(window, 50, 50);
          digit d2 = new digit(window, 300, 50);
          digit d3 = new digit(window, 450, 50);
          Rectangle colon1 = new Rectangle(225, 70, 40, 50);
          Rectangle colon2 = new Rectangle(225, 145, 40, 50);
          window.add(colon1);
          window.add(colon2);
          colon1.setBackground(Color.black);
          colon2.setBackground(Color.black);
          window.repaint();
Any help you can give me is greatly appreciated. Thanks!

Do me a favor just to humor me. Delete his paint() method override and substitute a paintComponent override that looks like so:
    public void paintComponent(Graphics g)
        super.paintComponent(g);
        g.setColor(getBackground());
        g.fillRect(0, 0, getWidth() - 1, getHeight() - 1);
        //repaint();
        // paintChildren(g);
    }Let me know what happens.
