Arrays.toString() not working?

no matter what i do Arrays.toString() does not work? i thought i was doing something wrong so i found a random code that uses Arrays.toString on stackoverflow to try and it wouldn't work with that too? Just checking here just incase it is an error on my part and not the Dr.java application.
