Question

Write a recursive method that displays an integer value reversely on the console using the following header:

public static void reverseDisplay(int value)

For example, reverseDisplay(12345) displays 54321. Write a test program that prompts the user to enter an integer, invokes the method above, and displays its reversal.

        System.out.print(value % 10);
        reverseDisplay(value / 10);


    }

    public static void main(String[] args) {

        Scanner scanner = new Scanner(System.in);
        System.out.println("Enter an integer number: ");
        int value = scanner.nextInt();

        reverseDisplay(value);
