Question

Hi all I can't understand why I don't have an imge on my screen. What's wrong?
public void paint(Graphics2D g2){
          g2.setColor(new Color(225,225,225));
          g2.fillRect(x, y, width, height);
          Image image= Toolkit.getDefaultToolkit().getImage(
                    "dog.jpg");
          g2.drawImage(image, x,y,null);
     }

Answer 1

Use ImageIO.read(url) and do it once, not in code that get calls repeatedly, like paintComponent or paint.
demo:
import java.awt.*;
import java.awt.image.*;
import java.io.*;
import java.net.*;
import javax.imageio.*;
import javax.swing.*;
public class ImageExample {
    public static void main(String[] args) throws IOException {
        URL url = new URL("http://blogs.sun.com/jag/resource/JagHeadshot-small.jpg");
        BufferedImage image = ImageIO.read(url);
        if (image == null) throw new NullPointerException();
        display(image);
    static void display(final Image image) {
        EventQueue.invokeLater(new Runnable(){
            public void run() {
                JPanel cp = new JPanel();
                cp.add(new JLabel(new ImageIcon(image)));
                JFrame f = new JFrame("ImageExample");
                f.setContentPane(cp);
                f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                f.pack();
                f.setLocationRelativeTo(null);
                f.setVisible(true);
}
