Concerning the OwlRacing project due a few days ago, the line you're talking about is treated as a class constant. Specifically referring to a line just inside the class header, this is what has been given to us:
public static final Scanner CONSOLE = new Scanner(System.in); // <- don't change this line!
I believe this line is treated as a class constant because its scope is the entire class, and not just one individual method. From this position, any method and any command inside this class can use Scanner type
CONSOLE to record user input and establish variables later down the road that are based on said input. I could be wrong, though, but this seems plausible to me.
