Spy number Example

So to check spy number in Java we need to follow the following steps.

Let’s implement the same in Java.

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

Scanner in= new Scanner(System.in);

int digit, num;

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

num = in.nextInt();

int product = 1;

int sum = 0;

//Extract digit, add to sum and multiply to product

while(num>0){

digit = num%10;

sum += digit;

product *= digit;

num=num/10;

}

if(sum == product)

System.out.println("Spy Number");

else

System.out.println("Not a Spy Number");

}

Output

Enter a number

1124
