    Default arrays

    Java Code:
        public static void main(String[] argv)
        {
            int[][] ia = new int[][]{{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
            System.out.println("Sum of first level: " + sumIntArray(ia[0]));
            System.out.println("Sum of this 2d array: " + sumIntArray(ia));
        }
        
        public static int sumIntArray(int[] ia)
        {
            int result = 0;
            for (int i: ia)
            {
                result += i;
            }
            return result;
        }
    
        // And to add another dimension
        public static int sumIntArray(int[][] ia)
        {
            int result = 0;
            for (int[] i: ia)
            {
                result += sumIntArray(i);
            }
            return result;
        }
