答：Server端程序:

packagetest;

importjava.net.*;

importjava.io.*;

publicclass Server{

privateServerSocket ss;

privateSocket socket;

privateBufferedReader in;

privatePrintWriter out;

publicServer(){

try{

ss=newServerSocket(10000);

while(true){

socket= ss.accept();

StringRemoteIP =

socket.getInetAddress().getHostAddress();

StringRemotePort = ":"+socket.getLocalPort();

System.out.println("Aclient come in!IP:"

+RemoteIP+RemotePort);

in= new BufferedReader(new

InputStreamReader(socket.getInputStream()));

Stringline = in.readLine();

System.out.println("Cleintsend is :" + line);

out=

newPrintWriter(socket.getOutputStream(),true);

out.println("YourMessage Received!");

out.close();

in.close();

socket.close();

}

}catch(IOException e){

out.println("wrong");

}

}

publicstatic void main(String[] args){

newServer();

}

}

Client端程序:

packagetest;

importjava.io.*;

importjava.net.*;

publicclass Client {

Socketsocket;

BufferedReaderin;

PrintWriterout;

publicClient(){

try{

System.out.println("Tryto Connect to

127.0.0.1:10000");

socket= new Socket("127.0.0.1",10000);

System.out.println("TheServer Connected!");

System.out.println("Pleaseenter some Character:");

BufferedReaderline = new BufferedReader(new

InputStreamReader(System.in));

out= new PrintWriter(socket.getOutputStream(),true);

out.println(line.readLine());

in= new BufferedReader(

newInputStreamReader(socket.getInputStream()));

System.out.println(in.readLine());

out.close();

in.close();

socket.close();

}catch(IOExceptione){

out.println("Wrong");

}

}

publicstatic void main(String[] args) {

newClient();

}

}
