用JAVA编写购物系统的代码是什么？（急）

算是最简单的吧

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");

}

static void choice1() {

System.out.println("购物管理系统客户信息");

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");

}

static void choice2() {

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");

break;

case 3:

choice2();

break;

case 4:

choice();

break;

}

如何编写Myshopping管理系统java程序代码

import java.util.Scanner;

public class AddCustomer{

public static void main(String[] args){

System.out.printIn("MyShopping管理系统客户信息管理添加客户信息\n");

int custNo; //会员号

int birthday; //会员生日

int points = 0; //会员积分

Scanner input=new Scanner(System.in);

for(int i=0;i3;i++){ //循环录入会员信息

System.out.printIn("请输入会员号（4位整数）:");

custNo = input.nextInt();

System.out.printIn("请输入会员生日（月\日用两位整数表示）:");

custNo = input.next();

System.out.printIn("请输入会员积分:");

custNo = input.nextInt();

if(custNo1000||custNo9999){ //会员号无效则跳出

System.out.printIn("客户号"+custNo+"是无效会员号！");

System.out.printIn("录入信息失败\n");

contiune;

}

System.out.printIn("您录入的会员信息是：");

System.out.printIn(custNo+" "+birthday+" "+points+ "\n");

}

System.out.printIn("程序结束！");

}

JAVA编写服装进销存管理系统源代码并且链接数据库

if (("+-*/".indexOf(conn)) != -1) {

d_one = jtx.getText();

operator = conn;

jtx.setText("");

return;

}

求高手给我个参考代码，我做半天没做出来。java的一个换购系统，题目如下

import java.util.Scanner; public class ChangeGoods { public static void main(String[] args) { System.out.println("输入消费金额："); Scanner scanner = new Scanner(System.in); String money = scanner.next(); int spendMoney = Integer.parseInt(money); System.out.println( "是否参加优惠换购活动?\n" + "1：满50元，加2元换购百事可乐饮料1瓶\n" + "2：满100元，加3元换购500ml可乐一瓶\n" + "3：满100元，加10元换购5公斤面粉\n" + "4：满200元，加10元可换购1个苏泊尔炒菜锅\n" + "5：满200元，加20元可换购欧莱雅爽肤水一瓶\n" + "0：不换购\n" + "请选择：" ); Scanner scannerInput = new Scanner(System.in); String select = scanner.next(); int option = Integer.parseInt(select); switch (option) { case 0: System.out.println("本次消费总金额：" + money); break; case 1: if(spendMoney=50){ System.out.println("本次消费总金额：" + (spendMoney + 2) ); System.out.println("成功换购：百事可乐饮料1瓶"); } break; case 2: if(spendMoney=100){ System.out.println("本次消费总金额：" + (spendMoney + 3) ); System.out.println("成功换购：500ml可乐一瓶"); } break; case 3: if(spendMoney=100){ System.out.println("本次消费总金额：" + (spendMoney + 10) ); System.out.println("成功换购：5公斤面粉"); } break; case 4: if(spendMoney=200){ System.out.println("本次消费总金额：" + (spendMoney + 10) ); System.out.println("成功换购：1个苏泊尔炒菜锅"); } break; case 5: if(spendMoney=200){ System.out.println("本次消费总金额：" + (spendMoney + 20) ); System.out.println("成功换购：欧莱雅爽肤水一瓶"); } break; default: break; } } }
