I've created a program that (hopefully) sorts a .txt file alphabetically. However, I'm having some difficulty actually using it. I'm trying to either use it in the interactions pane (I'm using Dr. Java) or in the terminal on my mac. When I use the interactions pane, a box pops up that takes in user input, but doesn't do anything as far as sorting. When I use terminal I get an error "could not find or load main class Radix sort.
This is my code for the program (I have separate class for the LinkedQueue and QueueADT that I know are functioning).
And the way I'm attempting to use this in the interface/terminal is by typing: java RadixSort<file path of the .txt file I'm attempting to sort
