Load Image

I would appreciate any helps.

Try:

ImageIcon initImage = new ImageIcon( this.getClass().getResource( "image.gif" ) );

   I tried it, it was ok when I compiled it.  However, it didn't show up the picture in image.gif

Can you post your actual code?

If you do:

    content = new JLabel (initImage);
    content.setText( "Label" ) ;

does the text show up?  (just checking you are actually seeing the label) ;-)

Ok, if your class is called:

    org.stuff.YourClass

and "image.gif" is in org/stuff

can you try:

    ImageIcon initImage = new ImageIcon( YourClass.class.getResource( "/org/stuff/image.gif" ) );

ie:  if the class is called YourClass (not in a package), and image.gif is in the same dir, can you try:

    ImageIcon initImage = new ImageIcon( YourClass.class.getResource( "/image.gif" ) );

  I added "content.setText("Label") into my code and "Label" showed up every time I clicked mouse.

  Here is my code:

  public class Cell extends JPanel{
 
  public static final int One = 1;
  public static final int Two = 2;
 
  private static final String  IMAGE_FILE_1 = "image1.gif";
  private static final String  IMAGE_FILE_2 ="image2.gif";
  private static final String  IMAGE_FILE_3 = "image3.gif";
 
  private JLabel content;
  private Point location;
 
  public  Cell(){
    this(null);
  }  
 
  public  Cell(Point pt){
//    ImageIcon initImage = new ImageIcon("image1.gif");
    ImageIcon initImage = new ImageIcon( this.getClass().getResource( "image1.gif" ) );
    setBackground(Color.white);
    setBorder(BorderFactory.createLineBorder(Color.black));
   
    content = new JLabel (initImage);
     
    add(content);
   
    location = pt;
  }  
 
  public Point getPosition(){
    return location;
  }  
 
  public void setContent(int image){
    switch (image){
      case One: content.setIcon(new ImageIcon(IMAGE_FILE_1));
                 break;
      case Two:  content.setIcon(new ImageIcon(IMAGE_FILE_2));
            break;
      default:              // do nothing
        break;
    }
  }
}

is Cell in a package?

if not, try:

----------

  public class Cell extends JPanel{
 
  public static final int One = 1;
  public static final int Two = 2;
 
  private static final ImageIcon image1 = new ImageIcon( Cell.class.getResource( "/image1.gif" ) ) ;
  private static final ImageIcon image2 = new ImageIcon( Cell.class.getResource( "/image2.gif" ) ) ;
  private static final ImageIcon image3 = new ImageIcon( Cell.class.getResource( "/image3.gif" ) ) ;
 
  private JLabel content;
  private Point location;
 
  public  Cell(){
    this(null);
  }  
 
  public  Cell(Point pt){
    setBackground(Color.white);
    setBorder(BorderFactory.createLineBorder(Color.black));
   
    content = new JLabel ( image1 );
     
    add(content);
   
    location = pt;
  }  
 
  public Point getPosition(){
    return location;
  }  
 
  public void setContent(int image){
    switch (image){
      case One: content.setIcon( image2 );
                 break;
      case Two:  content.setIcon( image3 );
            break;
      default:              // do nothing
        break;
    }
  }
}

 Compilation is successful, but the image didn't show up.  Cell is not in package.  Sorry, I am so tired.  I am going to sleep now.  I will chat with you later.  Thanks for your help.

Can I ask why the grade C?

Grade C means you couldn't be bothered to delete this question :-(    (https://www.experts-exchange.com/help.jsp#hi73)

Some sort of explanation why my comments were rubbish would have been nice...
