超市购物程序设计（java）

编写一个超市购物程序，在一家超市有牙刷、毛巾、水杯、苹果和香蕉五种商品，用户输入商品序列号进行商品购买，用户输入购买数量后计算出所需要花费的钱，一次购买结束后，需要用户输入“Y”或“N”，“Y”代表继续购买，“N”代表购物结束。商品价格如下表所示。

编程源代码：

package com.java;import java.util.Scanner;public class HelloWorld{    public static void main(String[] args){        String a = "Y";        double sum = 0.0;        do{                System.out.println("请输入购买的编号：");                Scanner sc = new Scanner(System.in);                int num = sc.nextInt();                switch (num) {                    case (1):                        System.out.println("请输入购买牙刷的数量:");                        int num1 = sc.nextInt();                        sum += num1 * 8.8;                        System.out.println("是否继续购物:");                        a = sc.next();                        break;                    case (2):                        System.out.println("请输入购买毛巾的数量:");                        int num2 = sc.nextInt();                        sum += num2 * 10;                        System.out.println("是否继续购物:");                        a = sc.next();                        break;                    case (3):                        System.out.println("请输入购买水杯的数量:");                        int num3 = sc.nextInt();                        sum += num3 * 18.8;                        System.out.println("是否继续购物:");                        a = sc.next();                        break;                    case (4):                        System.out.println("请输入购买苹果的数量:");                        int num4 = sc.nextInt();                        sum += num4 * 12.5;                        System.out.println("是否继续购物:");                        a = sc.next();                        break;                    case (5):                        System.out.println("请输入购买香蕉的数量:");                        int num5 = sc.nextInt();                        sum += num5 * 15.5;                        System.out.println("是否继续购物:");                        a = sc.next();                        break;                }        }while(a.equals("Y"));        System.out.println("这次购物的总价是:");        System.out.println(sum);    }}
