When adding a try / catch around the kart.drive(2); statement, the catch will define the error object thrown using (IllegalArgumentException iae). Here, iae will be an object containing the thrown error. This error object has a .getMessage() method. This can be printed out using the standard System.out.printf():

        try {
          kart.drive(2);
        } catch (IllegalArgumentException iae) {
          System.out.printf("The error was: %s\n", iae.getMessage());
        }
