IT技术System

用JAVA编写购物系统的代码是什么？（急）算是最简单的吧
【超市结算的java代码 java超市购物程序】package cn.job01;
import java.util.Scanner;
public class Lx07 {
public static void choice() {
System.out.println("登陆菜单");
System.out.println("1登陆系统");
System.out.println("2退出");
}

System.out.println("1显示所有客户信息");
System.out.println("2添加客户信息");
System.out.println("3修改客户信息");
System.out.println("4查询客户信息");
}

System.out.println("购物管理系统真情回馈");
System.out.println("1幸运大放送");
System.out.println("2幸运抽奖");
System.out.println("3生日问候");
}
public static void main(String[] args) {
choice();
Scanner input = new Scanner(System.in);
System.out.println("请输入1or2");
int num = input.nextInt();
switch (num) {
case 1:
System.out.println("主菜单");
System.out.println("1客户信息管理");
System.out.println("2购物结算");
System.out.println("3真情回馈");
System.out.println("4注销");
break;
}
System.out.println("选择输入数字");
int num1 = input.nextInt();
switch (num1) {
case 1:
choice1();
break;
case 2:
System.out.println("购物结算");

用java编程实现网上超市购物结算功能代码哎，超市结算的java代码我还是自己代码黏贴给你吧超市结算的java代码！免得总通不过！装不下这么多字，详情自己找我 。连接数据库类（添加修改会员信息） package com.to.java; import java.util.Scanner; import java.sql.*; public class Vds { Scanner Input=new Scanner(System.in);
