Question

Answer 1

You can use the below code to reverse a number using an array:

public static void reverse(int[] array) {

    if (array == null) {

        return;

    }

    int i = 0;

    int j = array.length - 1;

    int temp;

    while (j > i) {

        temp = array[j];

        array[j] = array[i];

        array[i] = temp;

        j--;

        i++;

    }

}

I hope this will help.
