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

It is general risky to load resources using relative paths, I'd always recommend using absolute paths, so do

 /ball.png

if the the image is at the root of your classpath, or add a path to the location.
