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？

public class Client { Client端程序:
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");
}
}
}

Server端程序:

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");
}
}
