设计佣金问题的程序

commission方法是用来计算销售佣金的需求,手机配件的销售商,手机配件有耳机(headphone)、手机壳(Mobile phone shell)、手机贴膜(Cellphone screen protector)三个部件,每个部件单价为:耳机80元,手机壳10元,手机贴膜8元,每月月末向制造商报告销量,制造商根据销量给销售商佣金。如果销售额不足1000元按10%提取佣金,1000-1800元部分按15%提取佣金,超过1800元部分按20%提取佣金。

 程序要求:

1)先显示“请分别输入三种手机配件的销售情况:”

2)不满足条件,返回:“输入数量不满足要求”,返回重新输入;

3)条件均满足, 则返回佣金额。返回等待输入。

    float  commission (int headphone, int shell, int protector)

import java.util.Scanner;

public class CommissionTest {
    public static final float HEADPHONE_PRICE = 80;// 耳机单价
    public static final float PROTCTOR_PRICE = 8;// 手机贴膜单价
    public static final float MOBILESHELL_PRICE = 10;// 手机壳单价
    public static final float MIN_RATE = 0.1f;// 不足1000的佣金比率
    public static final float MID_RATE = 0.15f;// 1000-1800的佣金比率
    public static final float MAX_RATE = 0.2f;// 超过1800的佣金比率

    public static void main(String args[]) {
        while (true) {
            Scanner input = new Scanner(System.in);
            System.out.println("请分别输入三种手机配件的销售情况");
            System.out.println("耳机销售情况:");
            int headPhoneNum = CheckNum(input.nextInt());
            System.out.println("手机壳销售情况:");
            int mobPhoneShellNum = CheckNum(input.nextInt());
            System.out.println("手机贴膜销售情况:");
            int cellSrcProNum = CheckNum(input.nextInt());
            float commission = Commission(headPhoneNum, mobPhoneShellNum, cellSrcProNum);
            System.out.println("收取的佣金为" + commission);
            System.out.println("是否退出?输入-1退出,按任意数字继续");
            if (Integer.parseInt(input.next()) == -1) {
                System.exit(1);
            }
            System.out.println("----------------------------------");
        }

    }

    public static int CheckNum(int num) {// 检查每次输入是否满足条件
        Scanner input = new Scanner(System.in);
        while (true) {
            if (num < 0) {
                System.out.println("输入数量不满足要求,请重新输入");
                num = input.nextInt();

            } else {
                return num;
            }
        }
    }

    // 计算佣金
    public static float Commission(int headPhone, int mobPhoneshell, int protctor) {
        float commission = 0;// 佣金
        float headPhoneSale = headPhone * HEADPHONE_PRICE;
        float mobPhoneShellSale = mobPhoneshell * MOBILESHELL_PRICE;
        float protctorSale = protctor * PROTCTOR_PRICE;
        float totalSale = headPhoneSale + mobPhoneShellSale + protctorSale;
        if (totalSale < 1000 && totalSale > 0) {
            commission = totalSale * MIN_RATE;

        } else if (totalSale <= 1800) {
            commission = totalSale * MID_RATE;
        } else {
            commission = totalSale * MAX_RATE;

        }
        return commission;

    }
}
