Write a java program to reverse number.

package com.tutorial4u;

import java.util.Scanner;

public class ReverseInteger {
       public static void main(String[] args) {
             int num,reverse=0;
             System.out.print("Enter any number to reverse : ");
             Scanner sc = new Scanner(System.in);
             num = sc.nextInt();
             while(num!=0){
                    reverse = reverse*10;
                    reverse=reverse+num%10;
                    num= num/10;
             }
             System.out.println("Reverse number is : "+reverse);
       }

}


Output: 


Enter any number to reverse : 2356
Reverse number is : 6532
