Question

所以我正在编写一个应该拿一个人工资（7.25美元）的程序并加上他们的佣金，然后吐出总额。我输入了所有请求的信息，我得到0.0的结果，这显然是错误的。感谢任何帮助，谢谢！这是我在驾驶员课程中的内容：

public static void main（String [] args）{

    Scanner input = new Scanner(System.in);
    double hours, sales, total;
    DecimalFormat df = new DecimalFormat("$0.00");
    Wages emp1 = new Wages();

    System.out.println("Please enter the hours worked: ");
    hours = input.nextDouble();

    System.out.println("Please the amount of sales: ");
    sales = input.nextDouble();




    System.out.println("Your total pay check wages are: " + df.format(emp1.getEverything()));

}

这里是我创建的工资类别：

    public class Wages {

private double PAY_RATE = 7.25;
public double sales, commission, total;
public int hours;

public Wages(){
}
public Wages(double rate,double sales, double total, double commission, int hours){
    this.sales = sales;
    this.total = total;
    this.PAY_RATE = rate;
    this.commission = commission;
    this.hours = hours;
}

public double getSales(){
    return sales;
}

public double getCommission(){
    if(sales >= 1.00 && sales <= 99.99){
        commission = (sales * 0.05);
        return commission;
    }
    else if(sales >= 100.00 && sales <= 299.99){
        commission = (sales * 0.10);
        return commission;
    }
    else if(sales >= 300.00){
        commission = (sales * 0.15);
        return commission;
    }
    return commission;
}
public double getEverything(){
    total = (PAY_RATE * hours) + commission;
    return total;
}

}

Answer 1

您已经创建了一个占用销售额和营业时间的构造函数，但您没有使用该构造函数，而是调用了默认值。

所以销售和工作时间没有价值。

Answer 2

如果我这样做，我会改变你的工资类别，包括：

public double hours; //You're taking a double for their input, so replace the int

public Wages(double hours, double sales){
    this.sales = sales;
    this.hours = hours;
}

//...

public double getEverything(){
    total = (PAY_RATE * hours) + getCommission();
    return total;
}

并在驱动程序中使用它：

System.out.println("Please enter the hours worked: ");
hours = input.nextDouble();

System.out.println("Please the amount of sales: ");
sales = input.nextDouble();

Wages emp1 = new Wages(hours, sales);

无法从创建的类中获得正确的输出（工资+佣金计算器）
