       for(i=2;i<=a;i++)

           f *= i;

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

   }

}

2. Using while loop.

public class Factorial{

   public static void main(String args[])  {

       int a=7,f=1,i=2;

       while(i<=a){

           f *= i;

           i++;

print("Factorial of 7 in while loop ")

while(I<7):

f * =I

I+=1

print("output:",f)
