请教一个Socket技术问题.

[FindingMyLeader]

高手，我写了一段程序：
是Socket通信的程序.
接收方源代码如下：

	}
	
	public void start(){

					byte[] bs = new byte[sss.length];

希望能够得到组织CSDN与路过的高手的点拨： 小弟的代码，为什么会有： 接收端能够运行出界面，但是发起端无法运行出界面，在进行debug调试的时候，会在第1张帖子中的MyClient3类型中的第“24行”代码的位置停止了. 之后小弟又对接收端进行了调试，停在这个位置： MyServer3这个类型中的第39行的：

String str = ss.read(s);

这个位置. 希望高手能够点拨： 为什么小弟的接收端停在具有阻塞功能的“read()”方法后，小弟的发起端也会停住？ 就停在这句建立连接的代码行上： s=new SocketClient("192.168.1.3",9999); 希望高手能够为小弟做一下分析： 小弟的代码现场的问题，出在什么位置？ 小弟在线等.

[FindingMyLeader]

其中的9999通信端口是通的. 小弟已经检查过了.

[java_liyi]

懒得看代码了 就发个链接你看看吧，我估计是一个问题 http://zhidao.baidu.com/link?url=rGfagL0ehpJG1gqlLqbzdHjIeZuBRa_HLCZ0nmracilAvXclKX2qSQxObGTGuzAUWVoZCyiXpFt6SmEza2m4eq

[Finding_ChenHaoNan]

是尚硅谷的李毅老师吗？！！！！！
哎呀妈呀！！！！！别跑了！！！！！！

谢谢李毅老师的点拨！！
我的错误已经解决！！
原因在这里：

这里，ObjectInputStream类的实例在进行new创建的时候，需要远程的发起方传过来一个Socket对象，从而对这个远程的Socket进行流的读取.
所以，在进行调试的时候，代码走到
s=new SocketClient("192.168.1.3",9999);
这里的时候，出现了：
停住.
的问题.
而在接收端，我的代码有这里的处理机制：

所以导致了“死锁”的“双向等待”的问题出现.
谢谢组织李毅大帝的相助！！！！！！
有李毅！！！！无懦夫！！！！
