茶叶销售系统java代码 茶叶销售管理系统论文

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;

}

}

}

Q2: 用JAVA的MyEclipse完成一个产品管理系统

1.解压你下载的销售系统.

2.找到里面的项目名 一般是英文或者拼音文件名

3.打开文件,查看里面是否是一个myeclipse项目文件.一般是有.myeclipse,.settings,.classpath,.mymetadata,.project 四个工程文件.(呵呵 一看就知道了).

4.打开myeclipse,在file下的import的弹出窗口里选择 General下的Existing Projects into Workspace 选择你刚刚解压的项目文件.

5.导入后可能会出现红叉,等右下框的process里的进度条没有时,如果还有红叉茶叶销售系统java代码，看看项目里面的文件茶叶销售系统java代码，如果是jsp报的红叉 可能是标签的原因造成的,可以不用管.右键你的项目 properties 点击 Java Build Path 看看里面的Source 编译的class路径选对没 是否是WebRoot 下的classes 文件夹，没有就需要建一个咯. 还有看看你的Library里的jar包等是否已经自动添加，如果一个也没有，需要手动添加,Add Jars 里面可以添加。

6.查看Java Compliler 下面选择的用的jdk 几编译的项目，改成你电脑里安装的jdk.

7.现在就需要配置数据库了,看看你下的项目里是否有说明使用的是什么数据库.

然后来看看你是否安装了如其所说的数据库.之后建立数据库,导入sql。完成数据库方面的配置,然后寻找项目中配置数据库连接的类或者页面,配置文件,将其中的什么url username password 等配置成你本机安装的数据库的url username,password 等等。完成后部署项目

8.使用tomcat 部署。将项目部署上，然后启动服务.如果控制台没有什么异常报出的话，大概可以打开浏览器 ： 项目名 一般就能看见项目的效果了.

9.你说的调试的话 在运行的时候就可以断点调试了。

以上说的有些多，但是较为详细了.希望对你有所帮助. 呵呵
