Chapter 18 Exercise 8, Introduction to Java Programming, Tenth Edition Y. Daniel LiangY.

18.8 (Print the digits in an integer reversely)
Write a recursive method that displays an int 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 and displays its reversal.

import java.util.Scanner;

public class Exercise_08 {

    public static void main(String[] args) {

        System.out.print("Enter an integer: ");
        int value = new Scanner(System.in).nextInt();
        reverseDisplay(value);

    }

    public static void reverseDisplay(int value) {

        if (value <= 0)
            return;

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