    {

        int x = 9;

        for (int i = 1; i <= x; i++)

        {

            for (int j = 1; j <= x - i; j++)

                System.out.print("   ");

            for (int k = i; k >= 1; k--)

                System.out.print((k >= 10) ? +k : "  " + k);

            for (int k = 2; k <= i; k++)

                System.out.print((k >= 10) ? +k : "  " + k);

            System.out.println();

        }

    }
