How to set an image as background in JFrame

Question

I can't figure out on how to fix the problem. Please help me. Thank you.

Here are the codes:

package com.gabriel.mvc.app;

import java.awt.Color;
import java.awt.Graphics;
import java.awt.Image;

import javax.swing.ImageIcon;
import javax.swing.JFrame;

import com.gabriel.mvc.shapeimpl.CarRenderer;
import com.gabriel.mvc.shapesfx.MyShape;
import com.gabriel.mvc.shapesfx.Renderer;

public class CarView extends JFrame {
    Image image;
    MyShape car;
    Renderer renderer = new CarRenderer();
    void init(MyShape car) {
        this.car = car;
    }
    void initUI() {     
        setVisible(true);
        image = new ImageIcon("2284910.jpg").getImage();
        setBounds(300,100,500,500);
        setSize(500,500);
    }
    
    public void paint(Graphics g)
    {
        g.clearRect(0,0,600,600);
        g.drawImage(image, 0, 0, null);
        renderer.draw(g, car);
    }
}

Here's the output, only solid color. Image not set as background. :(

Here's my expected output, I edited it on Photoshop.

You may refer on this code just replace your image source and add your CarRenderer after the drawImage method of Graphics.

import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.JDesktopPane;
import javax.swing.JFrame;
import java.awt.Image;
import java.awt.Graphics;

public class SampleImageBg extends JFrame{ 
    private JDesktopPane panel;

    public SampleImageBg() {
        panel = new javax.swing.JDesktopPane() {
            private Image image;
            {
                try {
                    image = ImageIO.read(getClass().getResource("bg.jpeg"));// source of your background image
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

            @Override
            protected void paintComponent(Graphics g) {
                super.paintComponent(g);
                g.drawImage(image, 0, 0, getWidth(), getHeight(), this);
                g.clearRect(50,0,300,300); // add your renderer here instead
            }
        };

        add(panel);
        setVisible(true);
        setSize(400, 600);
    }

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