Blackjack

how to think of this design from stratch?

casual thought: abstract cards /// how to play? //// what's the role in the game? ///what's the process of game?

game OOD thought path:

• (static)游戏道具和游戏状态的描述
• (dynamic)游戏规则和游戏流程

道具：

• card (注意，这个时候不要引入游戏具体的规则)
• deck(公共牌堆) 目前还不用考虑弃牌堆，只要考虑如果deck没有足够的牌，需要reset就好了
  • keep a list, store all the cards
  • keep a boolean array, index, left of which is used, right of which is not used,
  • set boolean array to the false, and shuffle the list.

游戏状态

• 公共牌堆的剩余的牌
• 每个玩家手里的牌，点数
• 玩家

step 1:

• Design a generic deck of cards

  • what kind of classes we need to define and

• write the suit, card, deck class

• for the deck class, there are some methods that we need to consider,

  • dealhand()
  • reset() -> shuffle()

step 2:

• design hand (手里的牌)
  • List<Card> or Card[]
  • addCards(Card[] ) 抓牌
  • int getScore()
• BlackJackHand extends Hand {...}
  • int getScore()...

step 3:

• How to simulate the BlackJack game?
• game status s1 -> rules + actions -> s2 -> check end ->continue;
  • shuttle
  • initialDeal
  • for (every hand) {
    • while (!checkhandend()) {
      • dealtHand()
    • }
    • // get the score for this player
  • declare winner
