Factorial – Java Program

Here is a simple Java Program that prints that Factorial of any number that user inputs. I have used a different function that is called to carry out the factorial.

package factorialfunction;

import java.util.Scanner;

public class facfcn {
public static void main(String args[])
{
Scanner scan = new Scanner(System.in);
System.out.println("Enter a number: ");
int a = scan.nextInt();
int b = factorizeFcn(a);
System.out.println("The answer is: "+ b);
}
public static int factorizeFcn(int c)
{
int fac = 1;
for (int i=1; i<=c; i++)
{
fac = fac * i;
}
return fac;
}
}
