Excessive

Today I had an in-class assignment in Java and while I did arrive late, the assignment didn't start until an hour into the class, so it was all good. We had a choice of two different problems, one was selecting random numbers between 1-99 and storing them in a data structure that wasn't array, ensuring there were no duplicate numbers and then printing the numbers to the screen. The second option was simply writing a function that will calculate the factorial of a number without use of recursion, and that seemed really easy to me, so I went with that.

It literally took me 2 minutes to write it, it was a one line for loop:

public static double calculateFactorial(int number){
   double factorial = 1;
   for(int i=number; i!=0; i--)
      factorial *= i;
   return factorial;
}
