一个简单的socket实例，大家看看有关问题出在哪

一个简单的socket实例，大家看看问题出在哪？
如题所示，我想实现在客户端输入的内容显示在服务端上，很简单的一个socket实例，可服务器端总是显示不出来，大家帮我看看问题出在哪？
服务器端代码：

Java code

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();                in = new BufferedReader(new InputStreamReader(socket                        .getInputStream()));                out = new PrintWriter(socket.getOutputStream(), true);                String line = in.readLine();                out.println("you input is :" + line);                out.close();                in.close();                socket.close();                ss.close();            }        } catch (IOException e) {        }    }    public static void main(String[] args) {        new Server();    }}

客户端代码：

Java code

import java.io.*;import java.net.*;public class Client {    Socket socket;    BufferedReader in;    PrintWriter out;    public Client() {        try {            socket = new Socket("127.0.0.1", 10000);            in = new BufferedReader(new InputStreamReader(socket                    .getInputStream()));            out = new PrintWriter(socket.getOutputStream(), true);            BufferedReader line = new BufferedReader(new InputStreamReader(                    System.in));            out.println(line.readLine());            line.close();            out.close();            in.close();            socket.close();        } catch (IOException e) {        }    }    public static void main(String[] args) {        new Client();    }}

[解决办法]
首先声明 本人新手 
如有错误 概不负责
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();
in = new BufferedReader(new InputStreamReader(socket
.getInputStream()));
out = new PrintWriter(socket.getOutputStream(), true);

String line = in.readLine();
//out.println("you input is :" + line);//你又写入输出流，当然不显示
System.out.println("you input is :" + line);
out.close();
in.close();
socket.close();
ss.close();
}
} catch (IOException e) {
}
}

public static void main(String[] args) {
new Server();
}
}
