java - 无法将数组列表分配给对象数组(Java)

Question

所以我正在尝试进行交易或不交易游戏，游戏尚未完成，但我遇到的最大问题是，当我尝试将数组列表分配给类型案例数组时，它似乎没有完成没有被分配。

我尝试调试，洗牌后输出正确，但我无法将结果分配给案例数组，以便我可以在游戏中使用它

下面是我分配的 3 门类(class)，我得到的结果是

我所说的这一行是可用案例的方法

Answer 1

您正在打印 case 对象而不是其值。使用 getValue (或 getFace)方法打印 value (或 >脸)。例如

for (int k = 0; k < cases.length; k++)
{
    System.out.println(cases[k].getValue());
}

如果您想同时打印 value 和 face，最好的方法是重写 toString 方法并在那里打印这些变量。
