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