Picture in a JFrame problem

[saytri]

I have inserted a picture in a JFrame. The problem is that the picture isn't appearing. Can someone pls tell me whats missing in my code? Thanks a lot.

This is my code:

Code:

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.io.*;
import javax.swing.*;
import java.util.Calendar;
import java.awt.image.*;
import javax.imageio.*;
 
    public class GQ extends JFrame implements ActionListener {
    private static final int FRAME_WIDTH = 1024;
    private static final int FRAME_HEIGHT = 768;
    private static final int FRAME_X_ORIGIN = 0;
    private static final int FRAME_Y_ORIGIN = 0;

 public static void main (String[] args) {
  
   GQ frame = new GQ();
   frame.setVisible(true);
    }

public GQ() {
       
   Container contentPane;  
        
    contentPane = getContentPane();
    contentPane.setBackground(Color.green);
        
    contentPane.setLayout(null);   

    image = new JPanel();
    contentPane.add(image);
}

class test4 extends JPanel {
BufferedImage image;
int w,h;

public test4() {
try {
image = ImageIO.read(new File("geo2.jpg"));
w = image.getWidth();
h = image.getHeight();
} catch (IOException ioe) {
System.out.println(ioe);
System.exit(0);
}
}

public Dimension getPreferredSize() {
return new Dimension(w,h);
}

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

g.drawImage(image,0,0,this);
}

public  void main(String[] args) {
JFrame f = new JFrame();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
test4 t = new test4();
t.setLayout(new BorderLayout());

f.add(t);
f.pack();
f.setVisible(true);
} 
         
          
    }

Thanks a lot.

    }

    public  void main(String[] args) {
        Test4Rx t = new Test4Rx("geo2.jpg");
        JOptionPane.showMessageDialog(null, t, "", -1);
    }
