Loading Images and Displaying them in NetBeans

  Asked By: Adelisa    Date: Aug 19    Category: Java    Views: 4927

This may seem a bit trivial, but it's been driving me nuts. I know
it should work, but it doesn't.

I've been reading "Learn Java In a Weekend". The author has a
picture displayed with his code, but for some reason, it's not
working when I build it using NetBeans.

First off, in NetBeans I put all my code in the java package named
FrameTest. In FrameTest, I have one java class called GUIFrame, and
a java main class called ImageTest. Ok, here's the code.

* GUIFrame.java
* Created on December 19, 2003, 9:53 AM

package FrameTest;
import java.awt.*;
import java.awt.event.*;

public class GUIFrame extends Frame implements WindowListener {

public GUIFrame(String title) {


/* Centers the Frame when setVisible(true) is called */
public void setVisible(boolean visible) {
if (visible) {
Dimension d = Toolkit.getDefaultToolkit().getScreenSize();
setLocation((d.width - getWidth())/2,
(d.height - getHeight())/2);

public void windowClosing(WindowEvent p1) {

public void windowDeactivated(WindowEvent p1) {}
public void windowClosed(WindowEvent p1) {}
public void windowDeiconified(WindowEvent p1) {}
public void windowOpened(WindowEvent p1) {}
public void windowIconified(WindowEvent p1) {}
public void windowActivated(WindowEvent p1) {}


* ImageTest.java
* Created on December 22, 2003, 10:47 AM

package FrameTest;
import java.awt.*;

* @author Student
public class ImageTest extends GUIFrame{

/** Creates a new instance of ImageTest */
public ImageTest() {
super("Image Test");
setSize(464, 288);

* @param args the command line arguments
public static void main(String[] args) {
new ImageTest().setVisible(true);

public void paint(Graphics g){
Image img = Toolkit.getDefaultToolkit().getImage
g.drawImage(img, 0, 0, 464, 288, this);

Here, I'm trying to load a file called FirstWorld.bmp. The file is
situated in my java package folder FrameTest. So its just in the
same folder as the GUIFrame and the ImageTest. Anyone see a problem
why the image cannot be displayed?

As far as I know, getImage() is supporting certain format only.
(Read the API). If you want to display the BMP format, I think
you need to get additional codec classes. (http://java.sun.

Try to change the bmp file to any JPG. It sure will work.
