  //1.创建扑克牌集合
  //创建map集合，类似于字典 和 list序号集合
  List list = new ArrayList();
  HashMap<Integer,String> map = new HashMap<Integer,String>();
  //将花色和数字及JQK组合添加进扑克牌集合map中
  String[] color = {"♥","♦","♠","♣"};

  //将序号集合打乱

  //3.分牌
  //创建三名玩家和底牌集合

  boardAssignment(map, player1);

  boardAssignment(map, player3);
  boardAssignment(map, cards);

  //4.看牌
  //打印输出三名玩家的牌的底牌
  System.out.println(player1);
  System.out.println(player2);
  System.out.println(player3);
  System.out.println(cards);
