Java game not working

I found this java source code for a brick breaker game online. I downloaded it and tried to run it but it gives me a NullPointerException. What is giving this exception and how do I fix it? Thanks.

Here is the stacktrace:

Apparently this code is supposed to work, but it isn't.

You probably didn't download the images as well, or at least didn't put them in the right folder. Make sure you put the images here:

Browse to Ball.java, go two folder levels up, create there a folder called images and put there your images.
