项目结构：

java开发之闹钟的实现代码1

效果图一：

java开发之闹钟的实现代码2

效果图二：

java开发之闹钟的实现代码3

效果图三：

java开发之闹钟的实现代码4

关于闹钟：

java开发之闹钟的实现代码5

复制代码 代码如下:

Alarm hongten v1.0

使用说明：

此文件夹中包括：

src文件夹 存放图片和声音文件夹，使用程序的时候，请不要删除此文件夹

alarm.jar 主要的功能程序jar包(要求安装jdk1.5或以上版本)

ReadMe.txt 说明文档

1.菜单功能说明

文件—— >

上传铃声(还没实现)

退出 功能：退出程序

工具—— >

截图工具 功能：进行截图

更改背景 功能：更改背景

帮助—— >

关于程序 功能：查看程序说明

2.设置闹表

2.1.可以在响铃时间里设置闹表时间

2.2.还可以用快速设置，+1表示在系统时间的基础上增加一分钟，-1表示在系统时间的基础上减去一分钟 (+5,+30,-5,-30同样原理)

3.提示铃声

可以选择铃声类型，进行试听，试听是时候可以停止(该功能还没完善)

4.系统托盘

4.1.在主窗体隐藏的时候，单击左键，主窗体可以显示出来；

4.2.在主窗体隐藏的时候，单击右键，可以进行功能选择：退出，恢复主窗体可见，截图

4.3.在设置的闹表时间剩下30秒是时候，系统会自动提示信息(电脑右下角会弹出消息提示框)

4.4.在设置更改背景的时候，同样会弹出提示信息(所有的提示信息会自动隐退)
