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;
}
}
}

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
