一、課程設(shè)計(jì)目的
本課程設(shè)計(jì)是利用Java進(jìn)行程序設(shè)計(jì)的一個(gè)關(guān)鍵實(shí)踐環(huán)節(jié)。它是根據(jù)教學(xué)計(jì)劃的要求，在教師的指導(dǎo)下，對(duì)學(xué)生實(shí)施程序設(shè)計(jì)訓(xùn)練的必要過程，是對(duì)前期課堂教學(xué)效果的檢驗(yàn)。其目標(biāo)在于培養(yǎng)學(xué)生綜合運(yùn)用面向?qū)ο蟮姆椒ㄍ瓿尚⌒蛙浖到y(tǒng)的分析與設(shè)計(jì)，熟練使用Java語言及JavaSE類庫完成桌面應(yīng)用軟件的開發(fā)和調(diào)試。通過這個(gè)課程設(shè)計(jì)，要求學(xué)生能夠遵循軟件開發(fā)過程的基本規(guī)范，按照課程設(shè)計(jì)的題目要求，獨(dú)立地完成設(shè)計(jì)、編寫、調(diào)試和測(cè)試應(yīng)用程序及編寫文檔的任務(wù)。
二、課程設(shè)計(jì)任務(wù)
通訊錄：
制作一個(gè)通訊錄程序，功能要求：
三、需求分析
所選擇的課題進(jìn)行需求分析，詳細(xì)描述所要實(shí)現(xiàn)的功能
需要實(shí)現(xiàn)的功能如下：
1.系統(tǒng)可以使用命令退出
2.信息的查詢：可以讓用戶選擇是否繼續(xù)查詢，或隨時(shí)結(jié)束
3.信息的添加
4.信息的刪除：當(dāng)用戶輸入未在通訊錄中的人時(shí)提示用戶重新輸入
5.信息的修改
6.信息的顯示
7.信息的拷貝：提示用戶要存放及查看的位置
8.返回主菜單：每項(xiàng)功能的使用完成后能夠返回主菜單選擇其他功能
四、系統(tǒng)設(shè)計(jì)
系統(tǒng)模塊劃分，描述類與類之間的關(guān)系
先考慮到通訊錄的內(nèi)容為：姓名與電話，所以建立聯(lián)系人實(shí)體類Contact
再考慮到系統(tǒng)功能為數(shù)據(jù)的增刪改查，所以定義了訪問數(shù)據(jù)的類Text
然后采用類MainMenu實(shí)現(xiàn)界面上顯示
五、系統(tǒng)實(shí)現(xiàn)
程序設(shè)計(jì)，核心模塊實(shí)現(xiàn)技術(shù)的說明
增添模塊：
?
?
刪除模塊：
?
?
修改模塊：
?
?
查詢模塊：
?
?
文件操作讀寫方法：
?
?
?
界面跳轉(zhuǎn)方法:
GoView()
六、總結(jié)
我的課程設(shè)計(jì)的基于Java的通訊錄系統(tǒng)。在一個(gè)月的課程時(shí)間里，通過不斷的查找資料，調(diào)試代碼和同學(xué)的幫助，完成了指定的系統(tǒng)的功能。通過這次課程設(shè)計(jì)，我加深了對(duì)Java程序的理解，熟練掌握了類的封裝等，并且能把它們運(yùn)用到實(shí)際的程序中去。
通過這次課程設(shè)計(jì)，我收獲的不僅僅是課程上的知識(shí)得到實(shí)際應(yīng)用，還有編程的基本習(xí)慣和開發(fā)系統(tǒng)時(shí)應(yīng)注意的流程。
