putting images in java applet using swing, which is coded in netbeans IDE.

[Kabir Shah]

I am a hobby programmer, however I am stuck in this java application of mine which has to put image from a directory. I have made a new package called finalconnect5.resources and also saved the image which I wanted to put in the GUI. I have tried to use the getSource() code but does not work.
I dont want to use the GUI builder, this has to be done via code,. How can I do it?

Here is what I tried to do private static final ImageIcon computerIcon = new ImageIcon(GomokuButton.class.getResource("finalconnect5.resources/Computer.png"));

but then got errors and following note.

Exception in thread "main" java.lang.ExceptionInInitializerError
at finalconnect5.Gomoku.createBoard(Gomoku.java:207)
at finalconnect5.Gomoku.<init>(Gomoku.java:51)
at finalconnect5.Gomoku.main(Gomoku.java:222)
Caused by: java.lang.NullPointerException

at finalconnect5.GomokuButton.<clinit>(GomokuButton.java:13)
... 3 more
Java Result: 1
BUILD SUCCESSFUL (total time: 2 seconds)

But for now putting some file from other file (which is physically located in my hard disk), all I am trying to get that image icon in my applet (using swing and the file formed is a ".jar" file)

Please help me. What should I do?

[Paul Clapham]

Since according to the API documentation for the getResource() method, the URL parameter is relative to the class which calls the method (in this case your GomokuButton class), my first advice would be to make sure you use an absolute URL, like this:

private static final ImageIcon computerIcon =
       new ImageIcon(GomokuButton.class.getResource("/finalconnect5.resources/Computer.png")); 

And of course make sure the image is actually in your jar file at that location.

No still the problem is there.

  package swinggui;
import javax.swing.*;
import java.awt.*;
/**
 *
 * @author Administrator
 */
 class gui extends JFrame{

    /**
     * @param args the command line arguments
     */
    public  gui()
    {
         super("GUI");
         setSize(300,300);
         setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         FlowLayout flow=new FlowLayout();
         setLayout(flow);
         JButton myButton=new JButton("OK");
         add(myButton);
         setVisible(true);
         JLabel icon=new JLabel("Hello");
         add(icon);
        myButton.setIcon(new javax.swing.ImageIcon("E:\\Java Programs\\FinalConnect5\\build\\classes\\finalconnect5\\resources\\Computer.PNG")); // NOI18N

    }


 }
 public class Main{
    public static void main(String[] args) {
        // TODO code application logic here
                  gui g=new gui();
                  

    }

}
  

Now the code is running but my system.is hanging.
I am trying to put this as my Image

Please help what should I do.

[Rob Spoor]

Your resource cannot be found, so getResource returns null. Can you show us the folder structure up to the resource?

[Rob Spoor]

The resource should be "/finalconnect5/resources/Computer.png" - all path parts must use / as a separator. That doesn't explain the OutOfMemoryError though. How big is that image?

[Kabir Shah]

The size of the image is 7.93 KB (8,125 bytes)
and the dimensions are 327x327

[Kabir Shah]

Thanks for replying but I have not fixed the problem.
Its about the dimensions of the picture.
I reduced it, and now got working.
