（如果我误用了任何术语，我道歉，我不是词汇最好的）我正在尝试编写一个程序，它迭代Person对象列表，并从随机列表中输出一个事件。对于只涉及一个Person的事件，它工作得很好，但对于多个Person，我在实现一个好的方法时遇到了麻烦。我已经通过手动从主文件调用Event方法使其工作。但这非常笨拙，而且很难在以后扩展，我想到了使用ArrayList和迭代作为实参参数的一部分的想法，因为这样更干净，更容易在以后扩展，但我遇到了一个奇怪的错误，我不知道如何修复。
这是我正在处理的三个文件。

每当我尝试运行代码时，当它尝试调用[Events.groupEvent（self，list.get（place+1））]时，它都会抛出以下错误：

Exception has occurred: java.lang.Error
"java.lang.Error: Unresolved compilation problem: 
    The method groupEvent(Person, Person) in the type Events is not applicable for the arguments (Person, Object)
"

ArrayList包含Person对象，至少在主文件中是这样，所以我不知道为什么它只是把它们当作泛型对象，当把列表作为参数使用时，我是做错了什么，还是你不能用ArrayList做这件事？
