It looks like a location problem because that code is perfectly fine for adding the icon   Since I don t know your folder structure  I suggest adding a simple check   File imageCheck   new File  water bmp     if imageCheck exists         System out println  Image file found    else      System out println  Image file not found       This way if you ever get your path name wrong it will tell you instead of displaying nothing  Exception should be thrown if file would not exist  tho

I think that your problem is in the location of the image  You shall place it in your source  and then use it like this     JButton button   new JButton      try       Image img   ImageIO read getClass   getResource  resources water bmp         button setIcon new ImageIcon img        catch  Exception ex        System out println ex         In this example  it is assumed that image is in src resources  folder
