Calculate Factorial Value of a number?

Factorial.java

import java.util.Scanner;
public final class Factorial {

	public static void main(String[] args) {
		Scanner s=new Scanner(System.in);
		System.out.println("Check Factorial number: ");
		int a=s.nextInt();
		int fc=1;
		int i=1;
		while (i<=a) {
			fc *=i;			
			i++;
		}
		System.out.println("Factorial Number is: "+fc);

	}
