上次做那個系統是swing+jdbc實現的，無奈被明哥一句否定，數據庫連接完全體現不了數據結構的作用，哎，這就是向小弟施加壓力呀。人無壓力不出油，經過10天的努力，終于李剛的通訊錄更新為1.1版本！

以下為設計思路，以及具體報告

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

李剛的通訊錄設計實驗報告

——信管1132班江錦泰

1）題目

李剛是一愛折騰的人，當然愛折騰的人均有夢想，他想當中國的蓋次呢?？刹?#xff0c;現在個人好友信息多了，復雜了，他想制作一個個人通訊錄的制作管理軟件。 剛好這個學期學了數據結構課，所以他準備使用數據結構知識來實現了。并考慮使用雙向鏈表作數據結構。并制定了初步要求：


（1）每個好友信息包含姓名、性別、住址、郵編、幾歲、電話、QQ、微信帳號、生日等。


（2）作為一個完整的系統，應具有友好的界面和較強的容錯能力

2）需求分析

一、運到相關數據結構基礎——雙鏈表

二、不能運動數據庫，即需要用到文件IO流，把人物信息記錄到相關文件當中

三、需要有增刪查基本功能

四、良好的交互界面

四、較好的容錯能力

3）概念結構設計

人物=｛姓名、性別、住址、郵編、幾歲、電話、QQ、微信帳號、生日｝

姓名為碼，電話為碼（key）

4）邏輯結構設計

一、雙鏈表，具體比較難實現，所以開展聯想，雙鏈表—>樹—>以樹為數據結構的集合（以下簡稱樹集）。

二、信息存到樹集。

三、樹集存到data文件

四、文件—>樹集—>改動數據—>文件

5）物理結構設計

一、建立data文件

二、構造人物類

三、構造樹集成為人物類的集合

四、構造良好的交互界面

6）系統實現與測試

簡單的一個包，AddressListTreeSet為樹集

Person類里面含有人物屬性集合

ShowJFrame為主界面

dat為存放人物信息的文件

這是主界面，左邊是一個JList姓氏導航，下面是一個功能面板，其中，按姓名查找與按電話號碼查找會讀取姓名框與電話框的內容

單擊導航框會跳轉

添加按鈕作用，如果任何一個輸入為空，會報錯，支持輸入不知道

點擊下來橫杠，點擊按姓名查找會進行查詢

電話號碼同理不做效果圖

刪除效果，選中任意一個，進行刪除，結束后讀入data

7）優缺點自我評價

一、AddressList1.1失去了1.0版本的界面美化性，也減少了界面的層數

二、缺少了修改功能，因實現比較復雜，時間又不可允許，故..

三、自己沒有充分利用好時間，總是在晚上編程

四、圖形交互界面以及數據結構部分內容還是不扎實，做的時候經常要看書，看CSDN，缺少效率

8）代碼展示，放碼過去！明哥接碼！
