		Scanner keyBoard = new Scanner(System.in);
		String answer = "";


		while (answer.compareToIgnoreCase("up") != 0 && answer.compareToIgnoreCase("down") != 0) {
			System.out.print("Do you want to count 'up' or 'down'?: ");
			answer = keyBoard.nextLine();
		}
		if (answer.compareToIgnoreCase("up") == 0) {
			for (int i = 1; i <= 5; i++) {
				System.out.printf("%-5d%-5d%-5d\n", i, (i + 10), (i + 100));
			}
		} else {
			for (int i = -1; i >= -5; i--) {
				System.out.printf("%-5d%-5d%-5d\n", i, (i + 10), (i + 100));
			}
