Java程序设计18223

1、Java程序设计课程设计报告题目：学生宿舍管理信息系统班级：计算机班姓名：谢梦媛 学号：12011247155目录一：程序设计的目的和意义二：程序设计：三：系统功能设计分析四：程序绘图效果示意图五：程序源代码及其分析说明六、总结七、个人心得体会学生宿舍信息管理系统的开发一、 程序设计的目的、任务和意义。1、 开发背景。在计算机越来越发达的今天,人们对计算机信息采集和保存的依赖越来越多,越来越离不开计算机,由此而产生的各种信息管理系统也越来越多,信息管理系统的发展日新月异,因此产生了各种能够很好的管理和保存信息，并且让人们使用方便的系统工具，所以我选择这个题目，因为可以通过制作该程序能更好的学习

2、编程知识，在以后的生活当中灵活应用。2、程序设计的任务。课程设计旨在在完成本课程的学习后，可以利用Java语言开发工具迅速地编写有一定实用价值的应用程序。课程设计中的问题比平时的习题复杂得多，也更接近实际。课程设计着眼于原理与应用的结合点，使学生学会如何把书上学到的知识用于解决实际问题，培养学生的动手能力；另一方面，使书上的知识变活，起到深化理解和灵活应用教学内容的目的。平时的习题局限于一个和二个知识点，而课程设计题是程序设计的综合训练，包括问题分析，总体结构设计，用户界面设计、程序设计、基本技能和技巧。本次课程设计要求学生能熟练运用eclipse和jdk工具包，掌握各种布局方式、异常处理、事

3、件监听与相应等基本知识点，实现对数据的添加、删除、修改、查询等基本功能的实现。最后能将自己的设计理念以及设计过程在文档中作出阐述与说明。3、 程序设计的意义我们可以看到如何运用自己已经掌握的知识，自己动手来完成一个Java绘图程序，通过整个流程的熟悉以及对程序组织结构和框架的理解，也可以极大的促进我们对Java程序程序设计的认识和掌握。通过本次课程的学习，我们可以更加系统地学习和了解如何从整体上设计和实现一个程序，这对我们今后学习、开发和设计更大更复杂的程序有着很大的帮助。二、 程序的设计1、 程序介绍本项目组设计的是学生宿舍信息管理系统，用户可以通过该系统对宿舍信息进行增、删、改、查。用户通

4、过登陆界面登陆进入宿舍信息管理系统，用户初次登陆密码与学号相同，进入后，用户可以选择添加成绩、删除信息、修改信息、查询信息。通过添加信息选项，用户可以录入自己的正确宿舍信息；通过删除信息；通过查询信息选项，用户可以选择查询某个学生的宿舍信息，也可以显示全部同学的信息。用户使用完毕后，点击退出，即可以退出该系统。所以通过这样的编程，让同学们可以的体验现在发展越来越好的信息化时代，不管从任何的方面。三：系统功能设计分析模块功能大概可以分为如下2个方面： 学生信息学生信息的输入，查询，删除。 成绩 根据学生的学号查询学生的宿舍信息。四：程序绘图效果示意图数据库添加信息删除信息修改信息查询信息用户登录
