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

    //HourlyEmployee = new HourlyEmployee (name, position, ratePerHour);
    hourlyEmployee.add(HourlyEmployee);
}

}

推荐答案

因为在该行中有两个同名的变量(即 salariedEmployee).这是适合您的修复程序:

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); 
}
