Why are we getting an error for System.out.printf/ln?

In the if statement, instead of "return" I wrote "System.out.println" and it gives me an IllegalArgumentException: bound must be positive. Why are we getting this kind of error?

If you are talking about the if-statment in the pickLunchSpot-method, you have to return a String, as the method expect a string return. You can use system.out.println too, but you have to return a string at the end. Else you need to change the return type of the method to be void instead of String.

use "\n" for a new line, System.out.print("\n"); or System.out.println();

also the printf expects an argument for each placeholder string
