Java getClass().getResource(“file”) leads to NullPointerException

Question

I am following the zetcode Snake java games tutorial and always get this error:

ImageIcon iid = new ImageIcon(this.getClass().getResource(\"ball.png\"));
bal         


        

Answer 1

Try this:

ImageIcon iid = new ImageIcon(this.getClass()
                  .getClassLoader().getResource("ball.png"));
ball = iid.getImage();

Make sure image is in the same folder as java file.
