Using JFileChooser to open and display an image

Hey everyone, okay so im pretty new to java, i normally use c but now im learning java...

What i need to do is open and select an image then display it the panel but am not sure how to do this..

this is what i have so far:

Code Java:

---

import java.io.*;
import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.awt.print.*;
import javax.swing.*;
import javax.swing.filechooser.*;
import javax.imageio.*;
 
 
public class assignment1 extends JPanel implements ActionListener {
	JLabel label = new JLabel();
	JMenuItem openItem, quitItem;
	BufferedImage image = null;
 
	public static void main(String[] args) {
		new assignment1();
	}
	public void actionPerformed(ActionEvent event) {
		JMenuItem source = (JMenuItem)event.getSource();
 
	if (source == openItem){
		JFileChooser chooser = new JFileChooser();
		chooser.setAcceptAllFileFilterUsed(false);
      chooser.setFileFilter(new ImageFilter());
		int retVal = chooser.showOpenDialog(this);
		if (retVal == JFileChooser.APPROVE_OPTION) {
				File myFile = chooser.getSelectedFile();
				try {
					image = ImageIO.read(myFile);
				}
				catch( IOException e ){ 
            e.printStackTrace(); 
				}
		}
	}	
	else if (source == quitItem){
		System.out.println("Quitting....");
		System.exit(0);
	}
}
 
 
	public assignment1(){
		JFrame frame = new JFrame("make window");
		frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		frame.setSize(400,200);
		//JPanel panel = new JPanel();
 
		//add menu bar.
		JMenuBar menuBar = new JMenuBar();
		frame.setJMenuBar(menuBar);
 
 
		//FILE MENU !!
		JMenu fileMenu = new JMenu("File");
		menuBar.add(fileMenu);
 
		//OPEN ITEM TOOL
		openItem = new JMenuItem("Open");
		openItem.addActionListener(this);
		fileMenu.add(openItem);
 
		//CLOSE ITEM TOOL
		quitItem = new JMenuItem("Quit Item");
		quitItem.addActionListener(this);
		fileMenu.add(quitItem);
		frame.setVisible(true);
		ImageDemo panel = new ImageDemo();
		frame.setContentPane(panel);
		//	JPanel panel = new JPanel();
	//	panel.setVisible(true);
	}
		public void paintComponent( Graphics g ){
			if( image != null ){
				Graphics2D g2 = (Graphics2D)g;
				System.out.println("Calling paint");
				g2.drawImage( image, 0, 0, null );
			}
		}
}

There are several parts to your problem. Which are you having trouble with?
Get the path to a file using JFileChooser
Read the file from the path as an image
Display the image in a JPanel.

Work on each of these steps one at a time and test/show the results using println() and then move to the next step.

I am able to select the file from the dialog box i want to know how to store that image in a buffer or somthing then display it under my menubar. thxs.

Look at the ImageIO class. It has methods for reading image files into Images.
