Java 对象数组-一副卡的数据存储不正确

我正在制作一个包含一副牌的程序。我知道有很多方法可以创建一副牌，但在本例中，我将每张牌都作为一个对象。此对象存储6个值：颜色、套装、面部、价值、等级和ID号

然后通过一种称为DeckOfCardsInitialiser的方法，52个卡片对象存储在一个数组中。此方法初始化卡，即计算并设置对象，即卡变量

当检查卡片是否正确设置时，我发现所有52张卡片都被分配给了仅用于最后一张卡片的值，在本例中为黑桃王。我已经做了一些调试，并且知道DeckOfCardsInitialiser正在按设计工作。它只是数组的对象，不能按计划工作

这是我第一次使用对象数组，因此我开始思考是否犯了一些愚蠢的错误。该程序运行于测试->卡片设计->卡片。我将按相反的顺序打印，以便更容易理解

}

您的类卡属性被定义为静态属性，这意味着它们对于类只存在一次

---

您必须从属性、getter和setter方法中删除static。

非常感谢Thomas，在过去的24小时里，这让我非常难过！
