用JAVA編寫購物系統(tǒng)的代碼是什么？（急）

算是最簡單的吧

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("購物結(jié)算");

break;

case 3:

choice2();

break;

case 4:

choice();

break;

}

}

}

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)無效則跳出

System.out.printIn("客戶號(hào)"+custNo+"是無效會(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編寫服裝進(jìn)銷存管理系統(tǒng)源代碼 并且鏈接數(shù)據(jù)庫

if (("+-*/".indexOf(conn)) != -1) {

if("".equals(d_one) "".equals(jtx.getText())) return;

d_one = jtx.getText();

operator = conn;

jtx.setText("");

return;

}

求高手給我個(gè)參考代碼，我做半天沒做出來。java的一個(gè)換購系統(tǒng)，題目如下

import java.util.Scanner; public class ChangeGoods { public static void main(String[] args) { System.out.println("輸入消費(fèi)金額："); Scanner scanner = new Scanner(System.in); String money = scanner.next(); int spendMoney = Integer.parseInt(money); System.out.println( "是否參加優(yōu)惠換購活動(dòng)?\n" + "1：滿50元，加2元換購百事可樂飲料1瓶\n" + "2：滿100元，加3元換購500ml可樂一瓶\n" + "3：滿100元，加10元換購5公斤面粉\n" + "4：滿200元，加10元可換購1個(gè)蘇泊爾炒菜鍋\n" + "5：滿200元，加20元可換購歐萊雅爽膚水一瓶\n" + "0：不換購\n" + "請(qǐng)選擇：" ); Scanner scannerInput = new Scanner(System.in); String select = scanner.next(); int option = Integer.parseInt(select); switch (option) { case 0: System.out.println("本次消費(fèi)總金額：" + money); break; case 1: if(spendMoney=50){ System.out.println("本次消費(fèi)總金額：" + (spendMoney + 2) ); System.out.println("成功換購：百事可樂飲料1瓶"); } break; case 2: if(spendMoney=100){ System.out.println("本次消費(fèi)總金額：" + (spendMoney + 3) ); System.out.println("成功換購：500ml可樂一瓶"); } break; case 3: if(spendMoney=100){ System.out.println("本次消費(fèi)總金額：" + (spendMoney + 10) ); System.out.println("成功換購：5公斤面粉"); } break; case 4: if(spendMoney=200){ System.out.println("本次消費(fèi)總金額：" + (spendMoney + 10) ); System.out.println("成功換購：1個(gè)蘇泊爾炒菜鍋"); } break; case 5: if(spendMoney=200){ System.out.println("本次消費(fèi)總金額：" + (spendMoney + 20) ); System.out.println("成功換購：歐萊雅爽膚水一瓶"); } break; default: break; } } }
