Java课程设计+文档+源代码(万年历+闹钟+记事本)

2015年12月18日一、课程题目设计一个万年历系统，实现以下功能（1）可以查看当前的年份、月份和日期；（2）有时间栏，便于用户查看当前时间；（3）能够查找1至9999年的日期与星期的关系。

其它功能可自行开发。

二、题目分析与设计1.使用的开发环境为eclipseJdk环境：jdk1.82. （此为万年历界面图）使用了jTabbedPane 类对功能页面分页，布局策略基本用BorderLayout 和GridLayout 。

3.本项共有5个类，基本一个功能有一个类实现，主类CalendarMain只包含一个main函数：对创建框架和其属性设置。

AlarmDemo类则实现闹钟功能；NoteBook 类实现记事本功能；CalendarsView 类则实现基本日历功能，ChooseDay 类是一个弹窗，被CalendarsView 调用，CalendarsView 、AlarmDemo 也在该类被调用；.new CalendarsView();4.日历界面使用了jTable ，功能的实现逻辑则是1.首先定义两个全局变量---年和月，查看不同时间的日历，该变量也随之改变。

2.写了几个函数获取今年第一天是星期几，然后根据月份天数即可推算具体某月第一天是星期几。

3.知道一个月第一天是星期几，则该月日历既可以顺序列出。

闹钟的功能实现思路：1.获取界面设定的时间。

2.使用线程，每过一秒急救获取当前时间，并判断是否到达设定的时间3.到设定的时间，启动弹窗，播放闹铃4.闹铃科根据文件选择器自行选择记事本功能实现思路1.在项目文件夹先新建一个txt文件作为储存的数据库2.利用File 类和io 数据流将界面文本储存进txt文件，实现保存功能3.每当程序启动，读取txt文件内容并显示到界面上三、测试分析1.使用如下拓展包2.程序界面截图如下日历主界面闹钟界面记事本界面3.测试流程及功能介绍（1）点击上一月、下一月可查看不同月份日历，左下角显示当前时间。

点击蓝色的日期栏可以回到当前页（2）点击圈中按钮会出现弹框，可以调节年、月，查看指定年月日历（3）闹铃可以使用默认闹铃，也能自定义选择闹铃，不过闹铃格式只能为wav或au时间到了以后出现弹框，并响起闹铃（4）记事本输入文本，按保存即可。

（5）点击最小化按钮，可以选择普通缩小或者直接缩小到托盘.附录：源代码(注：在工程目录下新建文件夹source ，并添加了闹铃文件，txt，托盘图片，如图)AlarmDemo.javaimport java.applet.Applet;import java.applet.AudioClip;import java.awt.BorderLayout;import
