Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

class Factoral
{
{
                                public static void main(String arg[])	
                                {
                                int n=5,fact=1;
 
                                for(int i=1;i<=n;i++)
                                {
 
        	   fact=fact*i;
                                }
 
 	        System.out.println("factoral="+fact);
                                }
}
