java - 数学值无法正确计算

由于某种原因，我得到的数学值与应该获得的值不同。我在这里做错了什么？

码：

overtimeHours = hoursWorked - 40;

regularPay = hourlyWage * hoursWorked - overtimeHours;
overtimePay = 1.5 * hourlyWage * overtimeHours;
totalPay = hourlyWage * hoursWorked + overtimePay;

输出：

Please enter employee's name: John
Please enter The Dragon's hourly wage: 22.50
Please enter how many hours The Dragon worked: 48.5

John's Wages
Regular Pay: $    1082.75
Overtime Pay: $    286.88
Total Pay: $    1378.13

最佳答案

运算顺序，就像您在基础数学中学到的一样。你在算

(hourlyWage * hoursWorked) - overtimeHours

相反，您想要

hourlyWage * (hoursWorked - overtimeHours)

另外，您不应该在total中重新计算。相反，只需添加定期和加班。

最后，正如@CodeMonkey所指出的，您无条件地假设此人正在加班。这是我的建议：

if(hoursWorked > 40) {
    regularHours = 40;
    overtimeHours = regularHours - 40;
} else {
    regularHours = hoursWorked;
    overtimeHours = 0;
}
