How can I create an Array in Descending Order?

I'm working on this project using Arrays. I have a method called createRandomIntArray that creates an array. This method is meant to return the Array in descending order. I have been able to do just that but I want to know if there is a more effective way to write this method than the way I wrote it. I have my code below.

    public static int[] createRandomIntArray(int n) {
        Random random = new Random();

        int[] result = new int[n];
        for (int i = 0; i < n; i++) {
            result[i] = random.nextInt(n);
        }
        Arrays.sort(result);

        for (int i = 0; i < result.length / 2; i++) {
            int temp = result[i];
            result[i] = result[result.length - i - 1];
            result[result.length - i - 1] = temp;
        }
        return result;
    }
