How do I add an image to a JButton

I am trying to add an image to a JButton and I m not sure what I m missing  When I run the following code the button looks exactly the same as if I had created it without any image attribute  Water bmp is in the root of my project folder    ImageIcon water   new ImageIcon  water bmp        JButton button   new JButton water       frame add button

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
