模拟一副扑克牌（不包括大小王），然后写一个方法，模拟洗牌行为。再写一个方法，将扑克牌发给4个玩家，最后输出每个玩家手里拿到的12张扑克牌。
public class MyTest02 { public static void main(String[] args) { List xiPai = xi_pai(); System.out.println(xiPai); System.out.println("=================="); // 洗牌 Collections.shuffle(xiPai); System.out.println("洗牌后：" + xiPai); // 四个玩家 ArrayList<Object> A = new ArrayList<>(); ArrayList<Object> B = new ArrayList<>(); ArrayList<Object> C = new ArrayList<>(); ArrayList<Object> D = new ArrayList<>(); //发牌 for (int i = 0; i < xiPai.size(); i ++){ if (i % 4 == 0){ A.add(xiPai.get(i)); }else if (i % 4 == 1){ B.add(xiPai.get(i)); }else if (i % 4 == 2){ C.add(xiPai.get(i)); }else if (i % 4 == 3){ D.add(xiPai.get(i)); } } // 输出玩家的底牌 System.out.println("玩家1" + A); System.out.println("玩家2" + B); System.out.println("玩家3" + C); System.out.println("玩家4" + D); } private static List xi_pai() { List list = new ArrayList<>(); String[] huase = {"梅花","方块","红心","黑桃"}; String[] num = {"A","1","2","3","4","5","6","8","9","10","J","Q","K"}; for (String h : huase) { for (String n : num) { list.add(h + n); } } return list; } }
