I am supposed to sort these objects based off of the region number. I tried a couple ways, but for some reason they all keep giving me an array or True or False values and not the objects themselves. I tried a compareTo method as well, but it kept giving me an int cannot be deferenced.
my code for StateController.

My Main class implements the drivers and that is working just fine.
If you need the State class to identify how that is made...

Any Ideas? I was told not to sort them, but just separate them by regionNumber. The region numbers are values 1-6.
