public static void sort(int[] array) { //write your code here for (int i = 0; i < array.length; i++){ array[i] = array[i] * -1; } Arrays.sort(array); for (int i = 0; i < array.length; i++){ array[i] = array[i] * -1; } }

You don't need to print array in sort method print array in main method. And also need to change the sort method.

public static void main(String[] args) throws Exception {
        BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
        int[] array = new int[20];

        for (int i = 0; i < 20; i++) {
            array[i] = Integer.parseInt(reader.readLine());
        }
        sort(array);
        for (int x : array) {
            System.out.println(x);
        }
    }

    public static void sort(int[] array) {
        Arrays.sort(array);
        int[] array2 = new int[20];

        for (int i = array.length-1; i >= 0; i--) {
            array2[array2.length-i-1] = array[i];
        }

        for (int i = 0; i < 20; i++) {
            array[i] = array2[i];
        }
    }

In your program, you are sorting the passed array in increasing order. You need to sort the array in DECREASING order, not instantiate a new array and sort that one.

But when I make the sort() method return a sorted array, I get an error because the method is supposed to be void!

You don't have to print anything in sort method
