A. java编写简单购物系统

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;
}
}
}

B. java超市计价系统代码

packageentity;


publicclassMarket{

privateintid;//id

privateintnum;//数量

privateStringgoods;//商品

privatedoubleprice;//价格


publicMarket(intid,intnum,Stringgoods,doubleprice){
super();
this.id=id;
this.num=num;
this.goods=goods;
this.price=price;
}

publicintgetId(){
returnid;
}


publicvoidsetId(intid){
this.id=id;
}


publicintgetNum(){
returnnum;
}


publicvoidsetNum(intnum){
this.num=num;
}


publicStringgetGoods(){
returngoods;
}


publicvoidsetGoods(Stringgoods){
this.goods=goods;
} publicdoublegetPrice(){
returnprice;
}


publicvoidsetPrice(doubleprice){
this.price=price;
}


publicdoublecalc(){

doublesum=price*num;

System.out.println("您消费共计:"+sum+"¥");

returnsum;

}

}
packagetest;

importjava.util.HashMap;
importjava.util.Map;
importjava.util.Scanner;

importentity.Market;


publicclassTest{

privatestaticMap<Integer,Market>goods=newHashMap<Integer,Market>();

publicstaticvoidmain(String[]args){

System.out.println("-------超市计价系统-------");

Stringgoods1="可口可乐";
Stringgoods2="爆米花";
Stringgoods3="益达";

printTable("编号","商品","价格");
printTable("1",goods1,"3.0¥");
printTable("2",goods2,"5.0¥");
printTable("3",goods3,"10.0¥");

goods.put(1,newMarket(1,1,goods1,3.0));

goods.put(2,newMarket(2,1,goods2,5.0));

goods.put(3,newMarket(3,1,goods3,10.0));

Scannerinput=newScanner(System.in);

System.out.println("请输入商品的编号:");

intnum=input.nextInt();

System.out.println("请输入商品的数量");

intamount=input.nextInt();

Marketmarket=goods.get(num);

market.setNum(amount);

market.calc();

}

privatestaticvoidprintTable(Stringrow1,Stringrow2,Stringrow3){

System.out.print(row1);

inttimes=12;

if(row2!="商品"){

times=5;

}

for(inti=0;i<times;i++){

System.out.print("");

}

System.out.print(row2);

for(inti=0;i<10;i++){

System.out.print("");

}

System.out.print(row3);

System.out.println(" ");

}

}
//测试结果:
-------超市计价系统-------
编号商品价格

1可口可乐3.0¥

2爆米花5.0¥

3益达10.0¥

请输入商品的编号:
3
请输入商品的数量
5
您消费共计:50.0¥

C. 求Java超市管理系统代码(急)

那很简单啊,界面用dreamweaver直接做就行 ,代码就是JAVA访问数据库,就那几行

D. 在线购物系统Java源代码

搜索引擎上搜索SHOP++,在线购物系统,JAVA源代码都有。

E. 求java购物系统代码

这些代码你应该自己去实现.
一个购物系统的代码你都叫别人帮你实现,你也太天真了吧.

F. 用java编程实现网上超市购物结算功能代码

哎,我还是自己代码黏贴给你吧!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); ZhuCK1 zhuck1=new ZhuCK1();

G. 跪求一个小型超市管理系统,用java编写的,急~ 只要源代码。。可以发我邮箱

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

public class Conn {
private static final String driver="com.mysql.jdbc.Driver";
private static final String url="jdbc:mysql://localhost:3306/blog?user=root&password=root";

//获得数据库连接
public static Connection getConnection(){
Connection conn = null;
try {
Class.forName(driver);
conn = DriverManager.getConnection(url);
if(conn != null){
System.out.print("成功");
}
} catch (SQLException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
return conn;

}

//关闭Resultset
public static void closeResultSet(ResultSet rs)
{
try
{
if(rs != null)
{
rs.close();
}
}catch (SQLException ex)
{
ex.printStackTrace();
}
}

//关闭Statement
public static void closeStatement(Statement st)
{
try
{
if(st != null)
{
st.close();
}
}catch (SQLException ex)
{
ex.printStackTrace();
}
}

//关闭Connection
public static void closeConnection(Connection conn)
{
try
{
if(conn != null)
{
conn.close();
}
}catch (SQLException ex)
{
ex.printStackTrace();
}
}

//测试数据库连接是否成功
public static void main(String[] args) {
Conn.getConnection();
}

}

H. 超市管理系统java完整源代码

…………一个相对完整的系统你想在网络知道找到……有点难度…………上CSDN找吧……

I. 求一个Java语言的超市收银系统源代码

刚好我们做了一个,一个是本地pos,一个是远程pos,远程用oracle数据库,本地用mysql数据库。可以断网用也可以连网用,别35金币了,十万就行了。

J. 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;
}
}
}
