Write a java program to find factorial of a number

Here we write a java program which find out the factorial of any number. 
Through keyboard we insert a number and get the factorial of that number.




public class FindFactorial
          {
                    public static void main(String as[])
                      {
                        //take input from keyboard
                       int a=Integer.parseInt(as[0]);
                       //initilize fact varialbe as 1
                           int fact=1;
                       System.out.print("factorial of number-"+a);
                         
                           for(int i=1;i<=a;i++)
                            {
                           fact=fact*i;
                          }
                       System.out.println("is :------"+fact);
                      }
         }
