全国交通咨询模拟(数据结构Java课程设计)

一、课程设计概述：使用语言：java编译环境：java虚拟机二、课程设计题目一[实验内容]全国交通咨询模拟[问题描述]1、管理员可以添加、修改、删除各交通路线信息。

2、用户查询从某一地点到另一地点的信息，提供查询转车次数最少、花费最少、所用时间最少的相关信息。

[需求分析]1、管理员和用户拥有不同的操作界面。

管理员从键盘输入个交通路线并保存在trainInformation.txt中。

2、对文件trainInformation.txt中的数据进行处理，要求具有如下功能：①、城市信息进行编辑。

②、对列车时刻表进行编辑（增设或删除）的功能。

③、提供三种最优决策：最省钱到达，转车最少。

④、提供各列车详细信息。

3、界面美观[概要设计]class MoneyLeast{}//求出两站点花费最少的路径class TrainContral{}//从文件中读出列车的所有信息或者将列车的信息写入到文件class TrainGraph{}//列车航线交通图class AdmFrame{}//管理员登陆界面class SearchInFrame{}//用户查询信息和显示信息界面[存储结构]class
