意味着我的所有计算都得到0并导致每周报告：
WEEKLY PAY REPORT FOR Wacky Widgets COMPANY
Employee
0
WEEKLY PAY
250
Total Payroll: $0.0
Total number of managers paid:1
Total number of Design Employees paid:1
Total number of Sales Employees paid:1
Total number of Manufacturing Employees paid:1
我需要帮助修复我的方法，这样他们就可以接受文件的整数并在计算中使用它们，因为我现在得到的所有数据都是0。如果需要，我可以提供我的读文件方法。感谢
这里是所有其他员工类型从中扩展的抽象类 [代码]

设计员工类

public double h;//hours worked

public void setRate(double rate) {

public void setH(double h) {
this.h = h;

销售员工
public class Sales extends Employee {
private double weekSales;
private final double pay = 250;
private final double percent = .057;
public Sales(String fName, String lName, String pos) {
// TODO Auto-generated constructor stub

return weekPay;
}
public double getWeekSales() {
return weekSales;
}
public void setWeekSales(double weekSales) {

}
我还有另外两种员工类型，但他们不需要在这里，因为如果我解决了这个问题，我可以解决其他问题。 这是我的公司课程，它读取文件a计算所有员工课程的每周工资和每周工资总额

答案 0 :(得分：0)
这很突出：
h = h * (3 / 2);
您在这里进行整数除法，因此您总是有效地乘以1。
将其更改为使用浮点值。
h = h * (3.0 / 2);
或者，明确说明你的乘法 - 你知道它总是一次半，所以我认为没有理由不这样做：
h = h * 1.5;
