I am new to the java swing library and am trying to create my own components. In this case I have a Circle class extending the JComponent class. However, when trying to add an instance of the Circle class to my JPanel, the circle isn’t displaying (only the JPanel).

I am aware that drawing directly to the JPanel with the Graphics class would be simpler, but I want to be able to create my own visuals class.

This is my code:

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

public class Main{
    public static void main(String[] args) {
        JFrame frame = new JFrame();
        JPanel myPanel = new JPanel();
        myPanel.setBackground(Color.CYAN);
        frame.setSize(500, 500);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        myPanel.add(new Circle());
        frame.add(myPanel);
        frame.setVisible(true);
    }
}

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

public class Circle extends JComponent {
    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);
        g.setColor(Color.RED);
        g.fillOval(50, 50, 100, 100);
    }
}

When running this code, only the cyan background of the JPanel is appearing. Is the JPanel covering the red circle? Have I overriden the paintComponent method incorectly?
