1.开始不知道如何实现在地图上的动态显示报警图片，后来通过查资料知道!了如下实现

2.在运行时遇到了程序无法显示图片的情况，总是抛出异常

五、用户手册1*本程序的运行环境为Windows操作系统，eclipse软件

2.点击进入系统后，会出现添加报警点，删除报警点，火灾报警模拟等功能

3.如果用户想要退出程序，直接点击运行界面的右上角上的关闭按钮即可，操作很方便

六、测试数据.开始界面1目录

一、需求分析3

二、概要设计3

三、详细设计3

四、调试分析15

五、用户手册15

六、测试数据15

七、附录20国主界面欢迎进入火灾报警模拟系统H弄天系统退出系统.点击进入后2屯功能选择界面添加火灾报警点删除火灾报警点火灾报警模拟退出.点击添加按钮3画添加火灾报警点报警点编目报警点名称报警点详细地址报警点隶属单位报警点X坐标报警点Y坐标返回确定.点击删除按钮4报警点编号确定返回.点击模拟按5钮.模拟的界面6

七、附录源程序文件清单

一、需求分析编写一个模拟火灾报警的系统，要求能够做到完成报警编号的录入，删除,修改，查询，删除功能，在某个地点按下报警，会显示出该地点的报警，并有报警声音程序执行的命令

1.进入系统的登录界面

2.进入系统后的界面选择

3.实现报警

二、概要设计

1.功能模块图

2.构程序中所使用的数据结构的介绍clas sGongNengJieMian extendsFrameimplements ActionListener{//实现接录的主界面//数据public classDBConnect源美
