1、Java程序設計課程設計報告題目：學生宿舍管理信息系統(tǒng)班級：計算機班姓名：謝夢媛 學號：12011247155目錄一：程序設計的目的和意義二：程序設計：三：系統(tǒng)功能設計分析四：程序繪圖效果示意圖五：程序源代碼及其分析說明六、總結七、個人心得體會學生宿舍信息管理系統(tǒng)的開發(fā)一、 程序設計的目的、任務和意義。1、 開發(fā)背景。在計算機越來越發(fā)達的今天,人們對計算機信息采集和保存的依賴越來越多,越來越離不開計算機,由此而產生的各種信息管理系統(tǒng)也越來越多,信息管理系統(tǒng)的發(fā)展日新月異,因此產生了各種能夠很好的管理和保存信息，并且讓人們使用方便的系統(tǒng)工具，所以我選擇這個題目，因為可以通過制作該程序能更好的學習

2、編程知識，在以后的生活當中靈活應用。2、程序設計的任務。課程設計旨在在完成本課程的學習后，可以利用Java語言開發(fā)工具迅速地編寫有一定實用價值的應用程序。課程設計中的問題比平時的習題復雜得多，也更接近實際。課程設計著眼于原理與應用的結合點，使學生學會如何把書上學到的知識用于解決實際問題，培養(yǎng)學生的動手能力；另一方面，使書上的知識變活，起到深化理解和靈活應用教學內容的目的。平時的習題局限于一個和二個知識點，而課程設計題是程序設計的綜合訓練，包括問題分析，總體結構設計，用戶界面設計、程序設計、基本技能和技巧。本次課程設計要求學生能熟練運用eclipse和jdk工具包，掌握各種布局方式、異常處理、事

3、件監(jiān)聽與相應等基本知識點，實現對數據的添加、刪除、修改、查詢等基本功能的實現。最后能將自己的設計理念以及設計過程在文檔中作出闡述與說明。3、 程序設計的意義我們可以看到如何運用自己已經掌握的知識，自己動手來完成一個Java繪圖程序，通過整個流程的熟悉以及對程序組織結構和框架的理解，也可以極大的促進我們對Java程序程序設計的認識和掌握。通過本次課程的學習，我們可以更加系統(tǒng)地學習和了解如何從整體上設計和實現一個程序，這對我們今后學習、開發(fā)和設計更大更復雜的程序有著很大的幫助。二、 程序的設計1、 程序介紹本項目組設計的是學生宿舍信息管理系統(tǒng)，用戶可以通過該系統(tǒng)對宿舍信息進行增、刪、改、查。用戶通

4、過登陸界面登陸進入宿舍信息管理系統(tǒng)，用戶初次登陸密碼與學號相同，進入后，用戶可以選擇添加成績、刪除信息、修改信息、查詢信息。通過添加信息選項，用戶可以錄入自己的正確宿舍信息；通過刪除信息；通過查詢信息選項，用戶可以選擇查詢某個學生的宿舍信息，也可以顯示全部同學的信息。用戶使用完畢后，點擊退出，即可以退出該系統(tǒng)。所以通過這樣的編程，讓同學們可以的體驗現在發(fā)展越來越好的信息化時代，不管從任何的方面。三：系統(tǒng)功能設計分析模塊功能大概可以分為如下2個方面： 學生信息學生信息的輸入，查詢，刪除。 成績 根據學生的學號查詢學生的宿舍信息。四：程序繪圖效果示意圖數據庫添加信息刪除信息修改信息查詢信息用戶登錄
