Palindrome Number Program in Java

A palindromic number is a number that remains the same when its digits are reversed. Like 16461, for example,

import java.util.Scanner;

public class PalindromeNumber
{
    public static void main(String[] args)
    {
        int n, num, r,
        rev = 0;
        Scanner sc = new Scanner(System.in);
        System.out.print("Enter number=");
        n = sc.nextInt();
        num = n;
        while (num > 0)
        {
            r = num % 10;
            rev = (rev * 10) + r;
            num = num / 10;
        }
        if (n == rev)
        {
            System.out.println("Palindrome Number");
        }
        else
        {
            System.out.println("Not Palindrome Number");
        }
    }
}

Output:

Enter number=12321
