Java blackjack deck class simply return the second card. The API is as follows:. Submit Card.

The specific goals are to:. After you draw a card, the number of cards in the deck should decrease by 1. Write resetDeck before writing and testing any other methods. If there are no cards to draw, throw an IllegalStateException. In this assignment, you will write a Card , Hand , and Deck class.
