我正在用 Java 编写一个程序，它是一款经典的 BlackJack 游戏。
规则是一样的，我们作为玩家和庄家（CPU）在某些规则下进行选择。
我的代码，在下面，制作了 2 个单独的牌组，一个供玩家使用，一个供经销商使用，每个都从不同的牌组抽牌，但我想让它们（玩家和庄家）都从同一个牌组抽牌（ s)。
对我的代码有任何建议/更正吗？

一些说明：
1）我们随机抽牌的方式是基于一种奇怪的方式，但这不是问题，它可以程序的方式确实从甲板上随机抽牌
2) 我注意到的另一个问题是，在 Hand 类中，我在 // 中的代码不起作用，因为它不允许我拥有 System.out.println()
Scanner input = new Scanner(System.in);
//Scanner input3 = new Scanner(System.in);
//int Decks = input3.nextInt();
River myRiver = new River();
//River myRiver = new River(Decks);
我想这样做是为了说明用户想玩多少套牌
