Question

我正在实施一个薪资系统，我需要在其中实施一个PayrollSystem类，将员工添加到ArrayList个员工，并为每个所述员工创建支票。我已经写了Employee和Paycheck个类，但是我遇到了PayrollSystem类的问题。

如何创建addEmployee方法？我是否将Employee对象与该员工的信息一起传递给它，还是有另一种方式？

员工：

package payrollSystem;

public class Employee {
    private String firstName;
    private String lastName;
    private int ID;
    private double hourlyWage;
    private double hoursWorked;

    public Employee(String first, String last, int id, double wage, double hours) {
        firstName = first;
        lastName = last;
        ID = id;
        hourlyWage = wage;
        hoursWorked = hours;
    }

    public void setFirstName(String first) {
        this.firstName = first;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setLastName(String last) {
        this.lastName = last;
    }

    public String getLastName() {
        return lastName;
    }

    public void setID(int ID) {
        this.ID = ID;
    }

    public int getID() {
        return ID;
    }

    public void setHourlyWage(double hourlyWage) {
        this.hourlyWage = hourlyWage;
    }

    public double getHourlyWage() {
        return hourlyWage;
    }

    public void setHoursWorked(double hoursWorked) {
        this.hoursWorked = hoursWorked;
    }

    public double getHoursWorked() {
        return hoursWorked;
    }

    public double calcPay(double wage, double hours) {
        wage = getHourlyWage();
        hours = getHoursWorked();

        return wage * hours;
     }
}

PAYCHECK：

package payrollSystem;

public class PayCheck {
    private String firstName;
    private String lastName;
    private int ID;
    private double netAmount;

    public PayCheck(String first, String last, int id, double wage, double hours) {
        firstName = first;
        lastName = last;
        ID = id;
        netAmount = wage * hours;
    }

    public String toString() {
        return "Paycheck issued for " + netAmount + "to " + firstName + ", "+ lastName + ", employee ID " + ID;
    }
}

PayrollSystem：

package payrollSystem;

import java.util.List;
import java.util.ArrayList;

public class PayrollSystem {
     public List<Employee> employees = new ArrayList<Employee>();
     public String companyName;

     PayrollSystem(String company) {
         companyName = company;
     }

     void addEmployee(Employee a) {
         employees.add(a);
     }

     void getHoursWorked(double hrs) {
         this.a.getHoursWorked();
     }

     void issueCheck() {
         double checkAmount = this.a.calcPay(a.getHoursWorked(), a.getHourlyWage());

         PayCheck check = new PayCheck(a.getFirstName(), a.getLastName(),  a.getID(), a.getHoursWorked(), a.getHourlyWage());

         check.toString();
     }
}

您可以制作addEmployee()方法。只要在某处创建员工，然后将其传递到payRoll类。

看起来像这样，假设你有一个List员工：

public void addEmployee(Employee employee){
    employees.add(employee);
}

在你的main中你可以去（假设myEmployee是一个雇员对象）：

PayrollSystem payrollSystem = new PayRollSystem();
payrollSystem.addEmployee(new Employee("John", "Smith", 1, wage, hours)); // Way 1
payrollSystem.addEmployee(myEmployee); // Way 2

Employee对象将包含Employee的所有信息。因此，当传入该Object时，所有信息都将随附。这允许您从payrollSystem中获取所有Employees，或使用内部方法对它们执行操作。
