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.掌握Java编程中的数据类型、变量、运算符、控制语句等基本概念。

3.学习Java中的类和对象的概念，理解封装、继承和多态的原理。

4.熟悉Java中的常用类库和方法。

5.能够运用Java编程语言编写简单的程序。

6.能够使用Java编程语言实现一个记事本应用程序，包括文本的增删改查等功能。

7.能够分析并解决编程过程中遇到的问题。

情感态度价值观目标：1.培养学生的团队合作意识和沟通能力，通过小组合作完成项目。

2.培养学生的创新思维和解决问题的能力，鼓励学生进行自主学习和探索。

3.培养学生的学习兴趣和自信心，让学生感受到编程的乐趣和成就感。

二、教学内容本课程的教学内容主要包括Java编程语言的基本概念和方法，以及记事本应用程序的设计和实现。

1.Java编程语言的基本概念和方法：–数据类型、变量、运算符、控制语句等基本概念。

–类和对象的概念，封装、继承和多态的原理。

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。
