简单黑白扑克牌游戏

1、1. 要求系统自动帮玩家抽2张卡，统计总数；电脑(delaer)自动抽两张卡，一张看得见一张看不见(用*表示)；然后玩家(player)选择是继续抽(HIT)还是停止抽(STAY)；再抽的话是抽一张牌，每次都统计总数；电脑的得分如果小于17的话他也会抽一张，大于等于17的话就不抽了；最后接近21的人赢，但不能超过21，超过就输了(BUST)，如果两个人的得分一样(tie)的话是电脑(dealer)赢。2. 效果3. 实现1）BlackJack.javapackage test;import java.util.ArrayList;import java.util.List;import jav
