java二人聊天工具。

把老师的代码拿来改了下，写了个程序。
一个TCPClient，一个TCPServer，简单的二人聊天。
难怪最多只能得六分（十分制），果然是很简单的。
没有写注释了，汗。。。
备忘，以后有空再说。。


/*

import java.io.*;

public class TCPClient {
public static void main(String arg[]) throws Exception{

String clientSentence;
String serverSentence;

Socket clientSocket = new Socket("192.168.0.100",1234);;


BufferedReader inFromServer = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
BufferedReader inFromClient = new BufferedReader(new InputStreamReader(System.in));
DataOutputStream outToServer = new DataOutputStream(clientSocket.getOutputStream());

while(true) {

clientSentence = inFromClient.readLine();
outToServer.writeBytes(clientSentence + '\n');

serverSentence = inFromServer.readLine();
System.out.println("FROM SERVER:" + serverSentence);
}
}
}
