            Scanner fileReader = new Scanner(new File(FILE_NAME));

            System.out.printf("%-20s%-10s%-10s%-10s%-10s\n", "Sample Data", "Game 1", "Game 2", "Game 3", "Average");
            int bowler = 1;
            while (fileReader.hasNext()) {
                String scores[] = fileReader.nextLine().split("\\s+");
                double average = Integer.parseInt(scores[0]) + Integer.parseInt(scores[1]) + Integer.parseInt(scores[2]);
                average /= 3;
                System.out.printf("%-20s%-10s%-10s%-10s%-10.2f\n", "Bowler " + bowler, scores[0], scores[1], scores[2], average);
                bowler += 1;
            }
            fileReader.close();

        }


}

(How can you edit the following source code, I dont wanna use filenotfound but throws ioexception. also i cant use split. please modify these two details for me. Can't use a method or advanced knowledge.
