Write a Java program that prompts the user to input an integer and then outputs the number with the digits reversed order

Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.Scanner;
 
public class JavaLoopExcercise
{
    public static void main(String[] args)
    {
        Scanner console = new Scanner(System.in);
 
        int number;
        int reverse = 0;
 
        System.out.print("Enter the number ");
        number = console.nextInt();
 
        int temp = number;
        int remainder = 0;
 
        while(temp>0)
        {
        remainder = temp % 10;
        reverse = reverse * 10 + remainder;
            temp /= 10;
        }
 
        System.out.println("Reverse of " + number + " is " + reverse);
    }
}

Result

Write a Java program that prompts the user to input an integer and then outputs the number with the digits reversed order
