(3)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 Main {
	
	private static Scanner scanner;

	/*
	 * 耳机80元，手机壳10元，手机贴膜8元
	 */
	public static float commission(int headphoneNum,int mpShellNum,int csProtectorNum){
		
		int total = headphoneNum*80+mpShellNum*10+csProtectorNum*8;
		float commission = 0;
		if(total<1000){
			commission = (float) (total*0.1);
		}else if(total>=1000 && total<=1800){
			commission = (float) (1000*0.1+(total-1000)*0.15);
		}else if(total>1800){
			commission = (float) (1000*0.1+800*0.15+(total-1800)*0.2);
		}
		
		return commission;
	}

	public static void main(String[] args) {

		String STYLE = "RUN";
		
		while(STYLE=="RUN"){
			System.out.println("请分别输入三种手机配件的销售情况(耳机,手机壳,手机贴膜)：");
			scanner = new Scanner(System.in);
			String input = scanner.nextLine();
			input = input.replaceAll("\\D", ",").replace("_+", ",");
			input = input.trim();
			
			String[] str = input.split(",");
			int[] nums = new int[str.length];
			float result = 0;
			boolean temp = false;
			String[] part = { "耳机", "手机壳", "手机贴膜" };
			if(str.length != 3){
				System.out.println("Error:输入数据格式错误,请检查并重新输入。");
				continue;
			}
			for (int i = 0; i < str.length; i++) {
				nums[i] = Integer.parseInt(str[i]);
				while (!temp) {
					if (nums[i] < 0) {
						System.out.println("Error:" + part[i]
								+ " 输入数量不满足要求，请重新输入"+ part[i]+ "销售数量。");
						@SuppressWarnings("resource")
						Scanner newNum = new Scanner(System.in);
						nums[i] = newNum.nextInt();
					}
					temp = true;
				}
				temp = false;
			}
			result = commission(nums[0], nums[1], nums[2]);
			System.out.println("总佣金为：" + result);
