Question

我必须创建一个程序，该程序必须包含三个或更多类，包括我的Main类，它将同时运行该类。现在，我有一个名为EmployeeRecord的类，它将为员工信息（员工全名，税号，员工ID和工资）创建数组，另一个名为Payroll的类，这是我遇到的最麻烦的类。在我的if和else if语句中，我在尝试编译说明＆＃34;不兼容类型时遇到错误：double无法转换为java.util.ArrayList。＆＃34;我无法理解或找到解决问题的方法。我已经为你发了两个班。感谢。

with multiprocessing.Pool() as pool, open(filename) as f:
    for result in pool.imap_unordered(somefunctionthatprocessesaline, f):
        ... do stuff with one result ...

}

Answer 1

你有

 ArrayList<Double> totalPay = new ArrayList<Double>();

然后：

 totalPay = totalHours * (employeeWages2.get(i - 1));

您的编译器是否没有告诉您行号？
