Java 的通信编程，编程题(或问答)，用JAVA SOCKET编程，读服务器几个字符，再写入本地显示？   
答:Server端程序:  
package test;  
import java.net.\*;  
import java.io.\*;   
public class Server  
\{  
 private ServerSocket ss;  
 private Socket socket;  
 private BufferedReader in;  
 private PrintWriter out;  
 public Server()  
 \{  
  try  
  \{  
   ss=new ServerSocket(10000);  
   while(true)  
   \{  
    socket = ss.accept();  
    String RemoteIP = socket.getInetAddress().getHostAddress();  
    String RemotePort = ":"+socket.getLocalPort();  
    System.out.println("A client come in!IP:"+RemoteIP+RemotePort);  
    in = new BufferedReader(new   
InputStreamReader(socket.getInputStream()));  
    String line = in.readLine();  
    System.out.println("Cleint send is :" + line);  
    out = new PrintWriter(socket.getOutputStream(),true);  
    out.println("Your Message Received!");  
    out.close();  
    in.close();  
    socket.close();  
   \}  
  \}catch (IOException e)  
  \{  
   out.println("wrong");  
  \}  
 \}  
 public static void main(String\[\] args)  
 \{  
  new Server();  
 \}  
\};  
Client端程序:  
package test;  
import java.io.\*;  
import java.net.\*;   
public class Client  
\{  
 Socket socket;  
 BufferedReader in;  
 PrintWriter out;  
 public Client()  
 \{  
  try  
  \{  
   System.out.println("Try to Connect to 127.0.0.1:10000");  
   socket = new Socket("127.0.0.1",10000);  
   System.out.println("The Server Connected!");  
   System.out.println("Please enter some Character:");  
   BufferedReader line = new BufferedReader(new   
InputStreamReader(System.in));  
   out = new PrintWriter(socket.getOutputStream(),true);  
   out.println(line.readLine());  
   in = new BufferedReader(new InputStreamReader(socket.getInputStream()));  
   System.out.println(in.readLine());  
   out.close();  
   in.close();  
   socket.close();  
  \}catch(IOException e)  
  \{  
   out.println("Wrong");  
  \}  
 \}  
 public static void main(String\[\] args)  
 \{  
  new Client();  
 \}  
\};
