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();

Java项目实训模拟网上超市购物结算功能

使用结构体+数组，就可以了

~~~~~~~~~~~~~~~~~~~~~~~~~

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;

}

问一下，这道题的java代码怎么编写。

package demo;

import java.util.Scanner;

public class practise {

public static void main(String[] args) {

System.out.println("**********");

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");

System.out.println("**********");

Scanner s = new Scanner(System.in);

System.out.println("请选择，输入数字：");

boolean isRight;

do{

isRight = true;

int choice = s.nextInt();

switch( choice ){

case 1:

System.out.println("执行客户信息管理");

isRight = false;

break;

case 2:

System.out.println("执行购物结算");

isRight = false;

break;

case 3:

System.out.println("执行真情回馈");

isRight = false;

break;

case 4:

System.out.println("注销");

isRight = false;

break;

default:

System.out.println("输入错误，请重新输入数字：");

}

}while(isRight == true);

System.out.println("程序结束！");

}

如何用Java语言编写购物结算系统

import java.util.Scanner;

//看这样的行吗？

public class StoreCharge {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.println("输入应付金额：");

double x = sc.nextDouble();

Price p1 = ampayable(x);

System.out.println(p1.toString());

System.out.println("输入实付金额：");

double y = sc.nextDouble();

Price p2 = ampaid(y);

System.out.println(p2.toString());

System.out.println("找零："+charge(p1,p2).toString());

charge(p1,p2);

}

public static Price charge(Price p1,Price p2){//p1总货价 p2收款

int c,b;

if(p2.connerp1.conner){

b = p2.conner+10-p1.conner;

p2.element = p2.element-1;

}else

b = p2.conner-p1.conner;

c = p2.element - p1.element;

return new Price(c,b);

}

public static Price ampayable(double x){//应付金额

Price a = new Price();

a.element = (int)x;

a.conner = (int)(x*10 -((int)x)*10);

return a;

}

public static Price ampaid(double x){//实付金额

Price a = new Price();

a.element = (int)x;

a.conner = (int)(x*10 -((int)x)*10);

return a;

}

class Price{

int element;//元

int conner;//角

public Price(){}

public Price(int e,int c){

element = e;

conner = c;

}

public String toString(){

return element+"元"+conner+"角";

}

用java怎么编写，求全代码

import java.util.Scanner;

import demo.ui.MainShell;

import demo.ui.PublicStatic;

public class DemoApp {

public static int getScanner() {

int input = 0;

try {

Scanner scanner = new Scanner(System.in);

input = scanner.nextInt();

} catch (Exception e) {

System.out.println("\t\t请重新输入");

return getScanner();

}

return input;

}

public static void main(String[] args) {

System.out.println("\t\t\t欢迎使用系统");

System.out.println("\t\t***********************");

System.out.println("\t\t\t1、客户信息管理");

System.out.println("\t\t\t2、购物结算");

System.out.println("\t\t\t3、真情回馈");

System.out.println("\t\t\t4、注销");

System.out.println("\t\t***********************");

while(true) {

int input = getScanner();

switch (input) {

case 1:

System.out.println("\t\t\t1、客户信息管理");

break;

case 2:

System.out.println("\t\t\t2、购物结算");

break;

case 3:

System.out.println("\t\t\t3、真情回馈");

break;

case 4:

System.out.println("\t\t\t4、注销");

break;

default:

System.out.println("\t\t请重新输入");

break;

}

if(input == 4) {

break;

}
