正在学计算机网络，照着书上的例子，参考了网上的一段代码，写了这个
在线程那段好像有点问题，运行是会有错误，其它还算正常
SSServer.class
import java.io.IOException;
import java.net.ServerSocket;
import java.net.Socket;
public class SSServer ...{
/** *//**

* @throws IOException
*/
public static void main(String[] args) throws IOException
...{
System.out.println ("Server starting... ");
ServerSocket server = new ServerSocket (10000);
while (true)
...{
Socket s = server.accept ();
System.out.println ("Accepting Connection... ");
new ServerThread (s).start ();
}
}
}
ServerThread.class
import java.io.*;
import java.net.*;
import java.util.*;
public class ServerThread extends Thread
...{
private Socket s;
ServerThread (Socket s)
...{
this.s = s;
}
public void run ()
...{
BufferedReader br = null;
PrintWriter pw = null;
try
...{
InputStreamReader isr;
isr = new InputStreamReader (s.getInputStream ());
br = new BufferedReader (isr);

try

}
catch (InterruptedException e)...{}
}

}
catch (IOException e)

}
SSclient.class
import java.io.*;
import java.net.*;
public class SSClient ...{
/** *//**

*/
public static void main(String[] args)
...{
String host = "localhost";
if (args.length == 1)host = args [0];
BufferedReader br = null;
PrintWriter pw = null;
Socket s = null;
try
...{

InputStreamReader isr;
isr = new InputStreamReader (s.getInputStream ());
br = new BufferedReader (isr);

pw.println ("DATE");
pw.println ("DATE");
pw.println ("PAUSE");

System.out.println (br.readLine ());
System.out.println (br.readLine ());
pw.println ("DOY");
System.out.println (br.readLine ());
}
catch (IOException e)
...{
System.out.println (e.toString ());
}
finally
...{
try
...{
if (br != null) br.close();
if (pw != null) pw.close();
if (s != null) s.close();
}
catch (IOException e )...{}
}
}
}
这样的三段代码，可以实现socket的互通信息，供大家参考！
