Thread: I get no error, my window opens, but the graphics don't show

I wrote a program to display a rectangle within a window, but it won't show. Is it because I didn't call the paint() method?
Sorry for indentation, I am using a text editor

import javax.swing.*;
import java.awt.Graphics; 
 
public class myGame {
public int x = 20;
public int y = 20;
myGame(){
JFrame f = new JFrame("The most advanced game in the world");
f.setSize(500,500);
f.setVisible(true);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public void paintComponent (Graphics g){
g.drawString("Hello",20,50);
g.drawRect(50,50,x,y);
g.fillRect(50,50,x,y);
}
public static void main(String[] args) {
 
new myGame();
}
}

Thanks for any and all help!

The beauty and "automatic" function of the paintComponent() method is when it overrides the parent's paintComponent() method, and usually the parent is a JComponent or a child of a JComponent (hence the name, paintComponent()). You have not yet learned the finer points of painting or drawing in/on Swing components, so I recommend you read the Custom Painting Tutorial. It's quite good and should open your eyes to new things.

So, I have to extend JComponent?
