Program Listing

 

import java.util.Scanner;

public class Reverse_Number {

    

    public static void main (String [] args)

    {

        

        int number=0, reverse=0;

        

        Scanner input = new Scanner (System.in);

        

        System.out.println("\n");

        System.out.println("\tReverse a Number in Java ");

        System.out.println("\n");

      

        System.out.println("\tGive Number : ");

        number= input.nextInt();

        

        int given_number = number; 

        

        while(number != 0)   

        {    

        int remainder = number % 10;  

        reverse = reverse * 10 + remainder;  

        number = number/10;  

        }  

        System.out.println("\n");

        System.out.println("\tThe given number is " + given_number);

        System.out.println("\tThe reverse of the given number is: " + reverse);  

        System.out.println("\n");

        System.out.println("\tEnd of Program");

        System.out.println("\n");

    }
