添加的问题从不同的类的对象变成一个ArrayList - java的

问题描述

我工作的一个项目在那里我有3个不同的类中创建对象CommissionEmployee，SalariedEmployee和HourlyEmployee。我需要这些主类添加到一个ArrayList，但不知道我要去哪里错了。

I'm working on a project where i have 3 different classes creating objects CommissionEmployee, SalariedEmployee and HourlyEmployee. I need to add these to an arraylist in the main class, but not sure where i'm going wrong.

公共类公司{

public String companyName;
public SalariedEmployee owner;
public ArrayList<SalariedEmployee> salariedEmployee;
public ArrayList<HourlyEmployee> hourlyEmployee;
public ArrayList<CommissionEmployee> commissionEmployee;


public Company (String companyName, SalariedEmployee owner){
    this.companyName = companyName;
    this.owner = owner;
}
public void addSalariedEmployee (SalariedEmployee SalariedEmployee){
    salariedEmployee.add(SalariedEmployee); **
}

public void addHourlyEmployee (HourlyEmployee HourlyEmployee){
    //HourlyEmployee = new HourlyEmployee (name, position, ratePerHour);
    hourlyEmployee.add(HourlyEmployee);
}
    public void addCommissionEmployee (CommissionEmployee CommissionEmployee){
    //CommissionEmployee = new CommissionEmployee (,, ratePerItem);
    commissionEmployee.add(CommissionEmployee);
}

** = this is the line where my editor is telling me i'm going wrong.Cheers, any help will be appreciated

推荐答案

由于您有在该行（即salariedEmployee）同名的两个变量。这是给你的修补程序：

Because you have two variables with the same name in that line (i.e. salariedEmployee). Here is the fix for you:

public void addSalariedEmployee (SalariedEmployee aSalariedEmployee){
    salariedEmployee.add(aSalariedEmployee);
}
