In this method i am reading the numbers into an array and then want the array to print numbers in reverse order, however i am doing something wrong here.

What I have tried:

Java
<pre>public void readAndReverse(int n)
    {
        int[] numbers = new int[n];
        Scanner scanner = new Scanner(System.in);
        // Read n integers into an array 
        for (int i = 0; i < n; i++) {
            numbers[i] = scanner.nextInt();
        }
        // Prints n integers in reverse order
        for( int i = 0; i < n; i++) {
            System.out.print(numbers[i] + " ");
            Collections.reverse(numbers[i]);
        }
    }

Think about the below for printing
for( int i = n - 1; i >= 0; i--) ....

To print in reverse order, you need to run the index from N - 1 downward to zero.
Your code runs up from zero to N - 1

If you really want to reverse the array (as opposed to show its items reversed) then have a look at this page: Reverse An Array In Java - 3 Methods With Examples[^].
