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.

import java.util.Scanner;

public class ReverseNumber {

    public static void reverseDisplay(int value) {

        if (value == 0) return;

        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);
    }
}

Write a RECURSIVE method that receives as a parameter an integer named n. The method will output n # of lines of stars. For example, the first line will have one star, the second line will have two stars, and so on. The line number n will have "n" number of ****** (stars) so if n is 3 it would print * ** *** The method must not have any loops!
