【问题描述】：
所以我有一个家庭作业要求我做以下事情：
- 公司最近更改了其年度总薪酬政策以提高销售额
- 销售人员将继续获得 55,000.00 美元的固定工资。当前每位销售人员的销售目标是 100,000.00 美元。
- 销售激励仅在达到 80% 的销售目标时才开始。目前的佣金是总销售额的 14%。
- 如果销售人员超过销售目标，佣金将根据加速因子增加。加速因子为 1.40。
- 应用程序应要求用户输入年度销售额，并应显示年度总薪酬。
- 应用程序还应显示销售人员本可以赚取的潜在年度薪酬表，以高于销售人员年销售额 5,000.00 美元的增量计算，单位为高于销售人员年销售额的 50%。
因此，这是我必须创建的表的示例，它假设年总销售额为 100,000.00 美元。所以它看起来像这样：
Total Sales Total Compensation
------------------------------------------------------------------
100,000 <<Program Calculated Value>>
105,000 <<Program Calculated Value>>
110,000 <<Program Calculated Value>>
115,000 <<Program Calculated Value>>
120,000 <<Program Calculated Value>>
125,000 <<Program Calculated Value>>
130,000 <<Program Calculated Value>>
135,000 <<Program Calculated Value>>
140,000 <<Program Calculated Value>>
145,000 <<Program Calculated Value>>
150,000 <<Program Calculated Value>>
上表是一个例子！它会根据输入的年销售额而有所不同。
应用程序还必须满足这些技术要求：
- 除了应用程序控制类之外，应用程序应该至少有一个类
- 您的代码必须使用一种方法来计算补偿
- 源代码必须演示条件和循环结构的使用
- 应该有适当的文档
基本上，我是在前几周的任务基础上构建的，该任务是构建一个计算销售人员年度总薪酬的应用程序。
- 销售人员将获得 55,000.00 美元的固定工资
- 销售人员还将获得佣金作为销售奖励。佣金是销售人员年销售额的百分比。目前的佣金是总销售额的 14%。
- 年薪总额为固定工资加上赚取的佣金。
所以，我遇到的问题是，我对此感到非常困惑。我收到一个错误，我将在下面显示，当我运行程序时，我得到了这个结果：
run:
This is a console based application that calculates the total annual compensation of a salesperson.
Just follow along with the prompts, and insert the correct data.
---------------------------------------------------------------------------
Enter salesperson's annual sales
/* NOTE: I INSERTED THE BELOW VALUE OF 100000 */
100000
Total annual compensation: $69000.00
0.0
$55000.00
Total Sales Total Compensation
ERROR: Please enter a valid sales amount.
Press enter to exit.
所以在while循环中我得到了错误：
'void' type not allowed here
'void' type not allowed here
not a statement
----
(Alt-Enter shows hint)
这里显示：
while (annualSales <= annualSalesTable) {
System.out.println(annualSales) + "\t" + calculate.printAnnualCompensation();
annualSales = annualSales + 5000;
}
我不知道如何解决这个问题。代码如下，主要有两个类SalesPerson.java，然后是Calculate.java：
SalesPerson.java：
package salesperson;
import java.io.IOException
import java.text.DecimalFormat;
import java.util.Scanner;
public class SalesPerson {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("This is a console based application that calculates the total annual compensation");
System.out.println("Just follow along with the prompts, and insert the correct data.");
System.out.println("----------------------------------------------\n");
getInput(in);
try {
System.out.println("Press Enter to exit");
System.in.read();
}
catch(IOException e) {
e.printStackTrace();
}
}
public static void getInput(Scanner in) {
Calculate calculate = new Calculate();
double annualSales;
try {
System.out.println("Enter salesperson's annual sales");
if(in.hasNextDouble()) {
annualSales = in.nextDouble();
if (annualSales == 0)
{
System.out.println("Please enter a valid annual sales amount.");
}
else
{
double tot = calculate.calcCompensation(annualSales);
DecimalFormat decFormat = new DecimalFormat(".00");
System.out.println("Total annual compensation: " + "$" + decFormat(tot));
/* NOTE: I DO NOT KNOW HOW TO GET annualSales to populate this! */
calculate.printAnnualCompensation();
System.out.println();
System.out.println("Total Sales\tTotal Compensation");
double annualSaleTable = annualSales * 1.5;
while(annualSales <= annualSaleTable) {
System.out.println(annualSales) + "\t" + calculate.printAnnualCompensation(); /* ERROR HERE */
annualSales = annualSales + 5000;
}
}
}
}
catch(Exception ex)
{
System.out.println("ERROR: Please enter a valid sales amount.");
}
}
}
这是Calculate.java 类：
package salesperson;
import java.text.DecimalFormat;
public class Calculate {
private double annualSales;
private double comissionRate = 0.14;
private double fixedSalary = 55000.00;
private double salesTarget = 100000.00;
private double accelerationFactor = 1.40;
public double calcCompensation(double annualSales) {
// Sets the annual salary to multiply by commission rate and then assign the total to currentComm
double currentComm = annualSales * comissionRate;
// Adds currentComm variable to the fixSalary variable and assigns that total to the "total" variable
double total = fixedSalary + currentComm;
return total;
}
public double getCommission() {
return this.annualSales * this.comissionRate;
}
public double annualSales(double anSales) {
annualSales = anSales;
return annualSales;
}
public void printAnnualCompensation() { /* THIS IS THROWING ERROR ON MAIN CLASS */
DecimalFormat decFormat = new DecimalFormat(".00");
/**
* Total sales that is less than 80% of the target = no commission
* Total sales that is between 80% of the target and the less than the target - 14%
* Total sales that is equal or exceeds the target sales is 14% * 1.4 or 19.6%
*/
double total = this.fixedSalary;
// Getting the percentage of the target achieved
double percentage = (this.annualSales / this.salesTarget) * 100;
System.out.println(percentage);
if (percentage < 80) {
// Do nothing, don't get commission if the percentage is less than 80% of target
} else if(percentage > 80 && percentage < 100) {
// Total = annualSalary + commission
total += getCommission();
} else if (percentage >= 100) {
// total = annualSalary + (commission * accelerationFactor);
total += (getCommission() * this.accelerationFactor);
}
System.out.println("$" + decFormat + format(total));
}
}
所以，这对我来说根本不起作用，我仍然需要我无法得到的桌子才能工作。我也需要它来满足要求，但对我来说，我似乎有很多代码只是无所事事，或者我正在复制所有内容，但我不知道如何清理它。
我不希望你们为我做这件事，我只是需要帮助，因为我越来越迷茫和沮丧！
感谢您能给我的任何帮助！
