I know that it is run in the main method, but don't know the proper syntax for calling them. For example, I know that (String[ ] args) holds an array of args[0] (my input file) and arg [1] (my output file). How do I use that to get my data? Thank you. -- "The man who does not read good books has no advantage over the man who cannot read them."

How do I use that to get my data? args[0] will be a String, so you probably want new File(args[0]), then read in the file, and populate some array with it. Afterwards, you’ll do new File(args[1]) and write out your data to it. See the whole java IO stuff.
