Java program to accept a number and check and display whether it is a spy number or not
Write a program to accept a number and check and display whether it is a spy number or not.
(A number is spy if the sum its digits equals the product of its digits.)
Example: consider the number 1124 , sum of the digits = 1 + 1 + 2 + 4 = 8
Product of the digits = 1 × 1 × 2 × 4 = 8
Solution
import java.util.*;
class SpyNumber
{
public static void main(String arr[])
{
Scanner sc=new Scanner(System.in);
int number,digit,product=1,sum=0;
System.out.println("Enter any Integer number:");
number=sc.nextInt();
while(number>0)
{
digit=number%10;
sum=sum+digit;
product=product*digit;
number=number/10;
}
if(sum==product)
{
System.out.println("It is Spy Number");
}
else
{
System.out.println("It is not a Spy Number");
}
}
}
Output
Enter any Integer number:
1124
It is Spy Number
-----------------------------------------
Enter any Integer number:
234
It is not a Spy Number
