//A small java program to calculate the Factorial
import java.util.Scanner;
public class Factorial
{
public static void main(String[] args)
{           final int fact;
             System.out.println("Enter a number to find the Factorial");
             Scanner in = new Scanner(System.in);
             fact=in.nextInt();
             System.out.println( "Factorial of " + fact + " is " + factorial(fact));
}

public static int factorial(int n)
{ 
             int result = 1;
for(int i = 2; i <= n; i++)
result *= i;
return result;
}

}

Output:

Enter a number to find the Factorial
