问题是:
设计一个薪资类,其中包含员工姓名,身份证号码,每小时工资率和工作小时数的字段。编写适当的访问器和mutator方法abd一个构造函数,该构造函数接受员工的姓名和ID号作为agruments。该班级还应该有一种方法,该方法返回员工的总薪酬,计算为工作小时数乘以小时工资率。编写一个程序,通过创建Payroll对象来演示该类,然后要求用户输入员工的数据。该计划应显示所赚取的总薪酬 这是我为班级所拥有的东西
Thread.Sleep
构造函数
import java.util.Scanner; //Needed for scanner class.
public class Payroll
{
private String EmployeeName;
private int IDnumber;
private double HourlyPayRate;
private double HoursWorked;
private double GrossPay;
/**
Constructor
@param Name The name to store in EmployeeName.
@param ID The ID to store in Employee ID number.
*/
public Payroll(String Name, int ID)
{
EmployeeName = Name;
IDnumber = ID;
}
public String getEmployeeName()
{
return EmployeeName;
}
public int getIDnumber()
{
return IDnumber;
}
public void setHourlyPayRate(double HourlyRate)
{
HourlyPayRate = HourlyRate;
}
public double getHourlyPayRate()
{
return HourlyPayRate;
}
public void setHoursWorked(double hoursWorked)
{
HoursWorked = hoursWorked;
}
public double getHoursWorked()
{
return HoursWorked;
}
public double getGrossPay()
{
return HourlyPayRate * HoursWorked;
}
}
当我编译它时,我没有得到任何错误,但我最后得到了grosspay = 0.0的结果。
答案 0 :(得分:0)
您创建了一个新的Payroll
对象
Payroll pay = new Payroll(EmployeeName, IDnumber);
并在print语句中调用getGrossPay()
方法
pay.getGrossPay()
该方法执行以下操作:
return HourlyPayRate * HoursWorked;
因为你从未设置HourlyPayRate
或HoursWorked
,当然该方法将返回0。
要解决此问题,请将这些值设置为您从用户读取的变量:
pay.setHoursWorked(HoursWorked);
pay.setHourlyPayRate(HourlyPayRate);
您可以在创建Payroll
对象之后但在调用getGrossPay()
方法之前添加这些行。因此,代码的最后四行现在应如下所示:
Payroll pay = new Payroll(EmployeeName, IDnumber);
//set pay rate and hours worked
pay.setHoursWorked(HoursWorked);
pay.setHourlyPayRate(HourlyPayRate);
//Get the Gross Pay of the employee.
System.out.println("The gross pay of " + EmployeeName + " is: " + pay.getGrossPay());
