Learn Shell Sorting using Java

class ShellSort {
    public static void main(String args[]) {
        int[] array = new int[] {
            3, 21, 0, 49, 7, 91, 110, 000, 14
        };
        int i, j, k, increment, temp, elements = array.length;
        /* Shell Sort Program */
        for (increment = elements / 2; increment > 0; increment /= 2) {
            for (j = increment; j < elements; j++) {
                temp = array[j];
                for (k = j; k >= increment; k -= increment) {
                    if (temp < array[k - increment]) {

                    } else {

                array[k] = temp;
            }
        }
        System.out.println("After Sorting we get:");

            System.out.println(array[i]);
