《Java实训》设计报告
项目名称：万年历记事本
石家庄科技信息职业学院
信息工程系
20##年5月30日
项目名称
一、项目需求
整合 万年历和记事本的功能，提供重要事件记录功能
（1）提供万年历功能
（2）整合记录事件功能
（3）可以修改设置时间
（4）考虑闰年2月
二、总体设计
本系统共包括1个Java源文件。
Java源文件及其功能如表1所示。
三、详细设计
1．唯一类claendar
（1）成员变量见表2变量表
（2）方法见表3方法表
（3）源代码见文件calendar.java
四．运行效果
1、程序打开时的效果，左边是记事本框，右边是万年历框。颜色和布局都是自己精心调配的，很美观。
2、月份下拉列表的视图，选择谋月很方便的。这也是选择下拉列表，没用输入框的初衷。
3、任选一个日期，在此日期中输入日记的信息。效果如下图：
3、保存日历成功对话框，当写完日记，选择“save”按键后自动弹出此对话框。
4、当想删除所写日记是=时，会弹出此项确认对话框。此确认对话框可有效防止误删。
5、删除成功后会显示此对话框，提示删除成功。
五、项目总结
本java文件整合记事本和万年历功能，而且可以添加重要事件功能，人性化的防误删功能，总体来讲，是一个比较全面的万年历记事本程序。
六、心得体会
通过制作这个程序，使我又学到了很多的知识，尤其是运用Java知识去解决实际问题的能力又得到了很大的提高。尽管所设计的程序比较简单，但是程序中的每个功能的实现都经过了自己的一定认真的思考。由于把所学的知识做到很灵活的运用在实际中，对于现在的我还有一定的难度，故而，在设计的每个的环节中，都会多多少少的遇到一些问题，这就促使我去查阅各种资料，或者请教老师和同学，极大的提高我的专业素养，同时对在有些书上的理论知识在实际的运用，以及应该注意的问题有了比较深刻的认识。当然，仍然有些理论问题不是很好的去运用，或者是了解的不深刻。这就使的在实践中的所设计的程序有些功能不是自己所想的那样的完美。不过，既然发现了问题的所在，我就不会放弃的，直至问题得到解决。这些也同时反映出了平时运用知识去实践这方面做的太少。太缺乏经验。对所设计中将所面临的问题认识不够。是Java课程设计让我认识到了这些问题的存在。同时给我提供了去面对这些问题的平台。也使我充分的认识到在以后也应该怎样去实践，怎样去学习一门计算机语言，以及如何去运用这门语言去解决实际问题等等。
总之，在经过这次Java的课程设计，使我认识到了自己很多的缺点，同时，也是我学到新知识和新方法的一个机会。这给我在以后继续学习好这门语言指明了方向。
