上述为“客户端”端点。
小弟运行上述两个类型的时候，首先运行了“服务器端点”，之后运行了“客户端端点”；
报出如下的故障：

高手，由于篇幅原因。下文请您见后面的补贴。
在此，感谢高手的过目！！

你的小问题太长，高手表示没有时间浏览，能否再精简下？

NewMoons哥，小弟的这个代码场景，已经全部把源代码贴完整了。您如果要浏览的话，只要把所有的类型拷贝到本地，就可以获得‘’调试模式”的状态了。 这个代码现场如果再精简的话，反而会耽误高手的过目时间。 希望高手，NewMoons哥，能够帮衬！！ 谢谢NewMoons哥的到场！！

[NewMoons]

我拷贝源代码的时候不是报重复就是还有找不到的类比如：ReadTxt、GetMyUserIP、DRecv0、ChatServer等等，太多列不完了。 你是不是从网上找的例子啊？ 一般来说，引起该异常的原因有两个： 1，如果一端的Socket被关闭（或主动关闭，或因为异常退出而 引起的关闭），另一端仍发送数据，发送的第一个数据包引发该异常(Connect reset by peer)。 2，一端退出，但退出时并未关闭该连接，另一端如果在从连接中读数据则抛出该异常（Connection reset）。简单的说就是在连接断开后的读和写操作引起的。 你的错误是客户端报的，那说明服务器端的socket不知什么原因断开了，检查下。

高手，上文中的代码，还有三个辅助类需要交待一下：

	BufferedReader br = null;
	PrintWriter pw = null;private Socket s;
	private InputStream in;
	private OutputStream out;
	private BufferedInputStream inByte;
	private OutputStream outByte;
	private BufferedReader inStr;
	private PrintWriter outStr;
	public String MyObjIP = "";
	private long size = 0;

	public SocketServer(int port) {
		try {
			ss = new ServerSocket(port);

	}
	
	public void setSocket(Socket so){

（上文为一个整合了两个存储了系统端点Socket水管的类型的源代码） 高手，由于篇幅原因，弟的帖子，有几个类型没有加导包语句。希望高手，能够知悉。 求高手支招： 小弟的代码，错在哪里？如何修改？

你的小问题太长，高手表示没有时间浏览，能否再精简下？
