    Default Accessing file

    Hi, I am writing a java application. I have my menu created, but the problem is displaying an image with it. I can do this if I give the full path to the image, but I have the image stored in a subfolder of the current directory called "Images". How can i display the image without giving the full path to it? Could someone give a code example please.

    Help is much appreciated.

    This is the hardest part of learning to use images in java.
    Java Code:
    import java.awt.GridLayout;
    import java.awt.image.BufferedImage;
    import java.io.*;
    import javax.imageio.ImageIO;
    import javax.swing.*;
    
    public class Test {
        public static void main(String[] args) throws IOException {
            String path = "images/hawk.jpg";
            BufferedImage image = ImageIO.read(new File(path));
            java.net.URL url = Test.class.getResource(path);
            System.out.println("url = " + url);
            BufferedImage image2 = ImageIO.read(url);;
            JPanel panel = new JPanel(new GridLayout(1,0,10,0));
            panel.add(new JLabel(new ImageIcon(image)));
            panel.add(new JLabel(new ImageIcon(image2)));
            JOptionPane.showMessageDialog(null, panel, "images",
                                          JOptionPane.PLAIN_MESSAGE);
        }
    }
    See the section Loading Images Using getResource in the Using Icons page.
    It has links to sections in the javadoc guides at the end of the section.
