'Fill an array with descending values

Trying to find the easiest way to fill an array with some values starting at 23 in descending order. I have the code below but not getting the result i am looking for:

int[] arr = new int[8];
int i = 24;
Arrays.fill(arr, --i);
System.out.println(Arrays.toString(arr));

output now

[23, 23, 23, 23, 23, 23, 23, 23]

expected

[23, 22, 21, 20, 19, 18, 17, 16]

How to fill an array easily and get the expected output, if possible without a for/while loop?

Solution 1:[1]

Why not simply use a for loop?

for (int j = 0; j < arr.length; j++) {
    arr[j] = i;
    i--;
}

You can also use the Arrays.setAll function

Arrays.setAll(arr, (index) -> i - index);

By the way, Arrays.fill will fill the all array with the given value, so that's why you're getting [23, 23, 23, 23, 23, 23, 23, 23].

Solution 2:[2]

You could use Streams :

IntStream.iterate(23, i -> i - 1)
            .limit(8)
            .toArray();

Solution 3:[3]

You'll need to write a for loop in descending order to complete and display the array.
