Example Program:
package day1; import java.util.Scanner; public class Factorial { public static void main(String[] args) { Scanner scan=new Scanner(System.in); System.out.println("Enter the factorial number"); int n=scan.nextInt(); long Factorial=1; for(int i=1; i<=n; i++) { Factorial=Factorial*i; } System.out.println(Factorial); } } Output:
