JAVA日历记事本课程设计报告

JAVA课程设计报告-日历记事本

同时还应具备提醒功能，当到达提醒时间时会自动弹出提醒。

2.需求分析日历记事本大致分为日历和记事两个部分。

①日历部分首先，需要选择日期，用户可以通过点击按钮选择前一年或后一年，同样也可以选择前一个月或后一个月，当月份为1月时，用户点击前一个月，会自动跳转到前一年的12月，同理，在12月时点击后一个月，会自动跳转到下一年的1月。

另外，当选择跨度比较大时，需要多次点击按钮，很不方便，所以需要一个下拉框，可以直接选择某一年或某一个月。

当用户改变选择日期时，日历会自动显示出这一个月的日历，并且可以通过点击某一天，来进行添加记事的操作，鼠标经过日历或点击日历时，会有不同的效果以提示用户这是可以点击的。

②记事部分首先，需要一个文本域给用户编辑记事内容，记事和日历部分所选择的日期是相关的，当用户点击日历选择某一天，则记事本上端会显示出选择的日期信息。

同时，记事应该还具有设置提醒的功能，用户点击设置提醒按钮后，会弹出一个新的对话框，用来选择提醒时间。

为保存记事，应将记事以文件的形式存储在计算机上。

另外，当用户想查看所有记事，或者想搜索某一则记事时，可以将日历部分换成一个表格，列出所有的记事，或者符合搜索结果的记事。

3.概要设计3.1功能结构日历记事本以功能划分，大致分为日历、记事列表及记事本三个部分：3.2布局软件界面的大致布局如下图，可以通过点击按钮将日历切换为记事列表4.详细设计及功能实现4.1结构①类结构②文件存储结构程序第一次运行时，会在设定的位置自动创建路径：“.../日历记事本/data/”。

2）培养掌握成学设计的基本思路和方法。

3）加强研发、调试程序的能力。

4）增强分析、解决问题的能力。

5）提高科技论文写作能力。

1.2 课程设计容设计GUI界面的日历记事本。

系统将日历、记事本功能结合在一起，用户可以方便地在任何日期记录下有关容或查看某个日期的记录容。

2 系统需求分析2.1 系统目标1．系统界面的左侧是日历。

该日历可以按年份前后翻动，鼠标单击“上年”按钮时，当前日历的年份减一；当鼠标左键单击“下年”按钮，当前日历的年份加一。

2．该日历也可以在某年按月前后翻动。

当鼠标左键单击“上月”按钮时，当前日历的月份减一；当鼠标左键单击“下月”按钮时，当前日历的月份加一。

3．使用鼠标左键单击选定的日期，如已有记录容，系统将弹出对话框提示该日已有记录容，并询问用户是否用记事本显示该容。

4．用户选择具体日期后，可以将记事本的当前容保存起来，形成日志。

2.2 主体功能用户可以方便地在任何日期记录下有关容或查看某个日期的记录容。

通过按按钮“上年”和“下年”对年份进行翻页。

通过按按钮“上月”和“下月”对月份进行翻页。

用户可以通过输入年份来查看自己的日志。

2.3 开发环境Windows XP；jdk1.5.0-0-05；ultraedit开发工具3 系统概要设计3.1 系统的功能模块划分与系统流程图本日历记事本共有4个java源文件。

技能目标：1. 能够运用所学知识，独立编写、调试和运行Java记事本程序；2. 培养良好的编程习惯，编写结构清晰、易于维护的代码；3. 学会使用集成开发环境（IDE）进行Java程序开发，提高编程效率。

情感态度价值观目标：1. 培养学生对编程的兴趣，激发学习积极性，增强自信心；2. 培养学生的团队协作能力，学会与他人分享和交流编程经验；3. 引导学生认识到编程在生活中的实际应用，培养创新意识和实践能力。

课程性质：本课程为实践性较强的Java编程课程，通过编写记事本程序，让学生掌握Java编程的基本知识和技能。

学生特点：学生处于初中或高中年级，具备一定的计算机操作能力和逻辑思维能力。

教学要求：结合学生特点，注重实践操作，激发学生的学习兴趣，培养编程技能，同时关注情感态度价值观的培养。

在教学过程中，将课程目标分解为具体的学习成果，便于教学设计和评估。

二、教学内容1. Java基本语法：变量、数据类型、运算符、控制语句（条件语句、循环语句）；2. 面向对象编程：类与对象、构造方法、封装、继承、多态；3. Java事件处理机制：事件监听器、事件适配器、事件处理方法；4. 用户界面设计：窗口、标签、文本框、按钮等组件的使用；5. Java文件操作：文件的读取与写入、文件的保存与打开；6. 集成开发环境（IDE）的使用：Eclipse或IntelliJ IDEA的基本操作与调试技巧。

教学大纲：第一周：Java基本语法及控制语句学习；第二周：面向对象编程基本概念及实现；第三周：Java事件处理机制及用户界面设计；第四周：Java文件操作及记事本程序编写；第五周：实践与调试，完善记事本程序。

1需求与总体设计
1.1需求分析
根据题目要求，将日历与记事本功能相结合，实现对某日期的事件进行记录的功能，设计出简洁方便美观的GUI界面。

将本程序主界面可以分为四个部分：日历日期信息展示、年份、月份、记事本内容、记事本下方的时钟，用四个类来实现其“日历”和“记事本”这两大功能。

通过主类CalendarPad创建动日历记事本软件的主界面，且该类中含有main
方法，程序从该类开始执行。

再用余下的year、mouth、NotePad类来显示并改变日期和实现记事本的功能。

1.2总体设计思路
1. 可以编辑日历的日期
2. 可以判断当前日期是否存在日志记录
3. 对有日志记录的日期,可以对该日期的日志记录进行修改和删除
4. 对没有日志记录的日期,可以创建并保存新建的日志记录
5. 对保存的日志加密，查看时得输入密码

1.2.2类图
2详细设计
2.1 CalendarPad类说明
该模块设计主要主要包含以下成员变量：
年(year)
月(month)
日(day)
存放日期的表(Hashtable)
存放日志的文件(File)
主要方法有：
创建程序主面板的构造方法（CalendarPad）
处理ActionEvent事件的接口方法（actionPerformed）
程序开始运行的main（）方法。
