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！");
}

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; } } }
