Blackjack Java Assistance

Hello,
I am supposed to turn this code into a blackjack program. I have the other files, that create the deck, the cards, and the driver. I have this, but I am not sure how to turn it into a running blackjack program. I don't understand this code. Can anyone help? 
Thanks
