簡單黑白撲克牌游戲

1、1. 要求系統(tǒng)自動(dòng)幫玩家抽2張卡，統(tǒng)計(jì)總數(shù)；電腦(delaer)自動(dòng)抽兩張卡，一張看得見一張看不見(用*表示)；然后玩家(player)選擇是繼續(xù)抽(HIT)還是停止抽(STAY)；再抽的話是抽一張牌，每次都統(tǒng)計(jì)總數(shù)；電腦的得分如果小于17的話他也會(huì)抽一張，大于等于17的話就不抽了；最后接近21的人贏，但不能超過21，超過就輸了(BUST)，如果兩個(gè)人的得分一樣(tie)的話是電腦(dealer)贏。2. 效果3. 實(shí)現(xiàn)1）BlackJack.javapackage test;import java.util.ArrayList;import java.util.List;import jav
