所以我正在编写这个二十一点程序，而我却无法将我的类数组转换为链接列表。我真的不知道从哪里开始，任何帮助都会受到赞赏。

一切都运行并且编译得很好而且有效。我只是不知道如何将其转换为链表格式

从链接：
＆＃34;要将数组转换为java.util.LinkedList，我们可以使用java.util.Arrays类的asList（）方法。 java.util包中的Arrays类提供了一个将数组转换为List的实用工具方法。 Arrays.asList（）方法将数组转换为固定大小的List。要创建LinkedList，我们只需要将List传递给java.util.LinkedList类的构造函数。也可以用这种方式创建java.util.ArrayList。＆＃34;
