用JAVA編寫購(gòu)物系統(tǒng)的代碼是什么？（急）

算是最簡(jiǎn)單的吧

package cn.job01;

import java.util.Scanner;

public class Lx07 {

public static void choice() {

System.out.println("登陸菜單 ");

System.out.println("1登陸系統(tǒng)");

System.out.println("2退出");

}

static void choice1() {

System.out.println("購(gòu)物管理系統(tǒng)客戶信息");

System.out.println("1顯示所有客戶信息");

System.out.println("2添加客戶信息");

System.out.println("3修改客戶信息");

System.out.println("4查詢客戶信息");

}

static void choice2() {

System.out.println("購(gòu)物管理系統(tǒng)真情回饋");

System.out.println("1幸運(yùn)大放送");

System.out.println("2幸運(yùn)抽獎(jiǎng)");

System.out.println("3生日問(wèn)候");

}

public static void main(String[] args) {

choice();

Scanner input = new Scanner(System.in);

System.out.println("請(qǐng)輸入1or2");

int num = input.nextInt();

switch (num) {

case 1:

System.out.println("主菜單");

System.out.println("1客戶信息管理");

System.out.println("2購(gòu)物結(jié)算");

System.out.println("3真情回饋");

System.out.println("4注銷");

break;

}

System.out.println("選擇輸入數(shù)字");

int num1 = input.nextInt();

switch (num1) {

case 1:

choice1();

break;

case 2:

System.out.println("購(gòu)物結(jié)算");

break;

case 3:

如何編寫Myshopping管理系統(tǒng)java程序代碼

import java.util.Scanner;

public class AddCustomer{

public static void main(String[] args){

System.out.printIn("MyShopping管理系統(tǒng) 客戶信息管理 添加客戶信息\n");

int custNo; //會(huì)員號(hào)

int birthday; //會(huì)員生日

int points = 0; //會(huì)員積分

Scanner input=new Scanner(System.in);

for(int i=0;i3;i++){ //循環(huán)錄入會(huì)員信息

System.out.printIn("請(qǐng)輸入會(huì)員號(hào)（4位整數(shù)）:");

custNo = input.nextInt();

System.out.printIn("請(qǐng)輸入會(huì)員生日（月\日用兩位整數(shù)表示）:");

custNo = input.next();

System.out.printIn("請(qǐng)輸入會(huì)員積分:");

custNo = input.nextInt();

if(custNo1000||custNo9999){ //會(huì)員號(hào)無(wú)效則跳出

System.out.printIn("客戶號(hào)"+custNo+"是無(wú)效會(huì)員號(hào)！");

System.out.printIn("錄入信息失敗\n");

contiune;

}

System.out.printIn("您錄入的會(huì)員信息是：");

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

}

System.out.printIn("程序結(jié)束！");

}

java商城系統(tǒng)那個(gè)比較好？

現(xiàn)在比較有名的有千米網(wǎng)B2C商城系統(tǒng)是Java開(kāi)發(fā)的，ecshop商城系統(tǒng)是PHP開(kāi)發(fā)的。相對(duì)來(lái)說(shuō)比較推薦千米的Java商城系統(tǒng)，各種功能都很齊全，而且易操作上手，安全性也有保障。具體的商城類型可以做獨(dú)立商城，也可以做多用戶商城，比如京東的模式。
