Given a number, and we have to check whether it is Spy number or not using Java program.

Spy Number

A number is a Spy number, if sum and product of all digits are equal.

Example:

Number 123 is a Spy number, sum of its digits is 6 (1+2+3 =6) and product of its digits is 6 (1x2x3 = 6), sum and product are same, thus, 123 is a spy number.

Program to check Spy number in java

import java.util.Scanner;

public class SpyNumber 
{
	public static void main(String[] args)
	{   
		int n,product=1,sum=0;
		int ld;

		// create object of scanner.
		Scanner sc = new Scanner(System.in);

		// you have to enter number here.
		System.out.print("Enter the number :" );

		// read entered number and store it in "n".
		n=sc.nextInt();

		// calculate sum and product of the number here.
		while(n>0)
		{
			ld=n%10;
			sum=sum+ld;
			product=product*ld;
			n=n/10;
		}

		// compare the sum and product.
		if(sum==product)
			System.out.println("Given number is spy number");
		else
			System.out.println("Given number is not spy number");
	}
}

Output

First run:
Enter the number :1124
Given number is spy number

Second run:
Enter the number :1123
Given number is not spy number
