继明哥的否定之后，java泰又出新作！明哥接码！

上次做那个系统是swing+jdbc实现的，无奈被明哥一句否定，数据库连接完全体现不了数据结构的作用，哎，这就是向小弟施加压力呀。人无压力不出油，经过10天的努力，终于李刚的通讯录更新为1.1版本！

以下为设计思路，以及具体报告

————————————————————————————————————————————————————

李刚的通讯录设计实验报告

——信管1132班江锦泰

1）题目

李刚是一爱折腾的人，当然爱折腾的人均有梦想，他想当中国的盖次呢。可不，现在个人好友信息多了，复杂了，他想制作一个个人通讯录的制作管理软件。 刚好这个学期学了数据结构课，所以他准备使用数据结构知识来实现了。并考虑使用双向链表作数据结构。并制定了初步要求：  
  
  
（1）每个好友信息包含姓名、性别、住址、邮编、几岁、电话、QQ、微信帐号、生日等。  
  
  
（2）作为一个完整的系统，应具有友好的界面和较强的容错能力

2）需求分析

一、运到相关数据结构基础——双链表

二、不能运动数据库，即需要用到文件IO流，把人物信息记录到相关文件当中

三、需要有增删查基本功能

四、良好的交互界面

四、较好的容错能力

3）概念结构设计

人物=｛姓名、性别、住址、邮编、几岁、电话、QQ、微信帐号、生日｝

姓名为码，电话为码（key）

4）逻辑结构设计

一、双链表，具体比较难实现，所以开展联想，双链表—>树—>以树为数据结构的集合（以下简称树集）。

二、信息存到树集。

三、树集存到data文件

四、文件—>树集—>改动数据—>文件

5）物理结构设计

一、建立data文件

二、构造人物类

三、构造树集成为人物类的集合

四、构造良好的交互界面

6）系统实现与测试

![Center][]

简单的一个包，AddressListTreeSet为树集

Person类里面含有人物属性集合

ShowJFrame为主界面

dat为存放人物信息的文件![Center 1][]

这是主界面，左边是一个JList姓氏导航，下面是一个功能面板，其中，按姓名查找与按电话号码查找会读取姓名框与电话框的内容![Center 2][]

单击导航框会跳转

![Center 3][]

添加按钮作用，如果任何一个输入为空，会报错，支持输入不知道

![Image 1][]

点击下来横杠，点击按姓名查找会进行查询

电话号码同理不做效果图

![Image 1][]

删除效果，选中任意一个，进行删除，结束后读入data![Center 4][]

7）优缺点自我评价

一、AddressList1.1失去了1.0版本的界面美化性，也减少了界面的层数

二、缺少了修改功能，因实现比较复杂，时间又不可允许，故..

三、自己没有充分利用好时间，总是在晚上编程

四、图形交互界面以及数据结构部分内容还是不扎实，做的时候经常要看书，看CSDN，缺少效率

8）代码展示，放码过去！明哥接码！
