int reversenum =0;

System.out.println("Input your number and press enter: ");

Scanner in = new Scanner(System.in);

num = in.nextInt();

while( num != 0 )

{

reversenum = reversenum * 10;

reversenum = reversenum + num%10;

num = num/10;

}

if (reversenum%2==0)

{

System.out.println("Reverse of input number is: "+reversenum);

else

System.out.println("Enter even number");

import java.util.*;

public class EveReverse

{

public static void main (String ar [])

{

System.out.println("Enter a number");

int n=sc.nextInt();

int r=0;

if(n%2==0)

{

while (n!=0)

{

r=r*10+(n%10); n/=10;

}

System.out.println("Number is even, Reverse if the number is:"+r);

}

else

System.out.println("Number not Even");

}

}                //ShortestCodePossible

Variable Description:-
