How to get min/Max value of a all column in a two-dimensional arra

so for example, lets say you have the following 2d array:

1 2 3
4 5 6
7 8 9

Than the out put should be:

-- col 1 --
min value at col 1 is 1
max value at col 1 is 7
-- col 2 --
min value at col 2 is 2
max value at col 2 is 8
-- col 3 --
min value at col 3 is 3
max value at col 3 is 9

public static void col(int[][] array) {

        for (int i = 0; i < array.length; i++) {
            int minValue =  array[i][0];
            int maxValue = array[i][0];
            for (int j = 0; j < array[i].length; j++) {
                if (minValue > array[j][i]) {
                    minValue = array[j][i];
                }
                if (maxValue < array[j][i]) {
                    maxValue = array[j][i];
                }
            }
        }

    }

getting an error:

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 3
