Dice code modification Question

Posted on 2007-12-03
Last Modified: 2008-02-01
The code below works for finding 5, 4, 3 and a pair for dice and compare hands. Now I would like to add a small and large straight and full house..(like a yahtzee hand). I plan on writing methods for the straights and full house...but my questions are:

1. Where would I need to add this in existing code.
2. I assume I would have to once determining either straight or flush I would have to assign a value for it...What would be good?

Some comments appreciated...

Excuse my ignorance, but how do you get a flush in dice - there are no suits..?

1. add a method (or define an interface and a class) for each check thats required.
2. value them based on their rank
