Write a program to accept a number through command line argument and find factorial of the number.

Program:-

class Fact

{

    public static void main(String args[])

     {

        if(args.length !=1)

         System.out.println("Wrong arguments");

        else

         {

            int n = Integer.parselnt(args[0]);

            int f=1;

            for(int i = 1;i<=n;i++)

                 f = f*i;

            System.out.println("Factorial of "+n+" is + f);

          }

      }

 }

 

 

 

OUTPUT:-

 

C:\java\bin>java Fact 5

Factorial of 5 is 120
