# Fascinating Number Program in Java

Example: 327

Multiply with 2:
327×2=654

Multiply with 3:
327×3=981

Now, concatenate the all number.
“327”+”654″+ “981”= 327654981

Here we can see that all digits from 1 to 9 are available in concatenating string.

``````
import java.util.Scanner;
public class FascinatingNumber
{

public static void main(String args[])
{
int num, num2, num3;
Scanner sc = new Scanner(System.in);
System.out.print("Enter any Number: ");
num = sc.nextInt();
num2 = num * 2;
num3 = num * 3;
String concatNumbers = num + "" + num2 +""+ num3;
System.out.println("Concated Number="+concatNumbers);
boolean flag = true;
for (char digit = '1'; digit <= '9'; digit++)
{
int count = 0;
for (int i = 0; i < concatNumbers.length(); i++)
{
char ch = concatNumbers.charAt(i);
if (ch == digit)
{
count++;
}
}
if (count > 1 || count == 0)
{
flag = false;
break;
}
}
if (flag)
{
System.out.println("Fascinating Number.");
} else
{
System.out.println("Not a Fascinating number.");
}
}
}
``````

#### Output:

```Enter number=23
Binary of 23=10111
Evil Number
```
