public static void sortArray (int[] array) {
    int j = 0, k = 0, temp = 0;

    for (j = 0; j < array.length; j++) {
        for (k = j; k < array.length - 1; k++) {
            if (array[k] > array[k + 1]) {
                temp = array[k];
                array[k] = array[k + 1];
                array[k + 1] = temp;
            }
