Java 程序设计实验报告年级、专业、班级2011级计科3班2011级计科3班姓名江唯伟张桉实验题目网络白板的设计与实现实验时间2013.11.11实验地点主教0414实验成绩 实验性质验证性 设计性 综合性教师评价：算法/实验过程正确； 源程序/实验内容提交 程序结构/实验步骤合理；实验结果正确； 语法、语义正确； 报告规范； 其他： 评价教师签名：一、实验目的综合利用Java GUI、Java Graphics、多线程和网络技术编程实现网络白板程序。网络白板是一种基于网络的程序，用户可以通过该程序将文字、图片等传输给其他用户查看。二、实验项目内容1、根据系统要求，完成系统需求分析。2、设计并实现相关的数据交换协议。3、设计并实现相应的数据同步协议。4、实现简单的图元，如文字以及简单的几何图形的绘制。5、实现简单图元的网络传输，以及用户之间的文字交流。6、按照实验要求，更强大的功能活动更多的分数。三、实验过程或算法（源程序）要求：写明设计思想、程序的结构、功能关系图、类的说明并按照UML的规范画出类之间的关系图、程序执行流程图，最后是源代码。设计思想：服务器：创建对象输入输出流实现网络通信handleMessage处理所有对基本图形的操作的消息接收到客户端添加基本图形消息：1.将添加对象加入到白板已有对象的类中2.通知所有客户添加图形对象用户移动图形的消息处理：1.将原来位置的对象提取出来2.添加到要被删除的列表中3.通知所有客户更新画板用户退出的消息处理登陆界面比较简单，采取自定义布局。程序的结构：src文件夹里包含mywb文件夹和images文件夹，其中mywb文件夹中有23个java项目文件。功能关系图：部分UML图：FillOvalObj( ):setPara( )getType( )getBounds( )paint( )getColor( )LoginFrame( ):LoginFrame( )init( )actionPerformed( )LoginMessage( ):LoginMessage( )getList( )getRlines( )getId( )PaintObjects( ):add( )addElementWithID( )replaceObject( )replaceObjWithID( )getObjectId( )elements( )clone( )ServerAddObjMessage( ):ServerAddObjMessage( )getID( )getElement( )ServerReplacedMessage( ):ServerReplacedMessage( )getOldID( )getID( )getObject( )WhiteBoardFrame( ):WhiteBoardFrame( )init( )jbInit( )addMouseListener( )status( )destroy( )getLocalIP( )WhiteBoardPanel( ):WhiteBoardPanel( )setType( )WBMouseListener( )mouseReleased( )WBMouseMotionListener( )setColor( )paint( )WhiteBoardServer( ):WhiteBoardServer( )run( )handle( )handleMessage( )NotifyRanLine( )notifyAll( )WhiteBoardThread( ):WhiteBoardThread( )run( )readMessage( )程序执行流程图： 开始 输入姓名，可更改IP和端口 选择自己喜欢的图形和颜色进行绘画 退出源代码：主要代码如下：WhiteBoardFrame:public class WhiteBoardFrame extends JFrame private String serIp = null;
