Hello All,
I'm getting this error and really don't see where I am erring. A previous version I have runs fine in eclipse and from the commandline, however this doesn't :


The class file is :

Other than removing some comments and debugging System. out() statements, this is the same file that still works in the earlier incarnation. Any help, or quicker eyes, would be welcomed. Thanks.

V.

You get a NullPointerException because something is null that shouldn't be. It happens while sorting the array, so perhaps one of the array elements is null. Take a look at how you assign values to your array.

Its throwing a NullPointer in compareTo. So the missing element might be he culprit.

Thanks Stephan,Rob, and Mohamed! I am embarrassed to say, I totally missed it... Apparently I need to take a break and go do some suburi. Again, thanks so much for your assistance. Take care.
