很简单的程序，求解

public class Server{ 
    private ServerSocket ss; 
    private Socket socket; 
    private BufferedReader in; 
    private PrintWriter out; 

    public Server()
    { 
        try 
        { 
            ss = new ServerSocket(6000); 

            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(); 
    }

}

public Client()
{
try
{
socket = new Socket("192.168.1.2", 6000);
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(); 
}

}

这个程序为什么从客户端发消息服务器没反应呢？求解，我菜鸟，急求哈~~~

[code="java"]
public class Server{
private ServerSocket ss;
private Socket socket;
private BufferedReader in;
private PrintWriter out;

public Server()
{
try
{
ss = new ServerSocket(6000);

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();
}
}

out.println(line.readLine());
line.close();
out.close();
in.close();
socket.close();
}
catch (IOException e)
{}
}

public static void main(String[] args)
{
new Client();
}
}
[/code]

刚刚给你的程序加了行号。
地址：192.168.1.2换成127.0.0.1看看行不行！
（还有Clinet这个类去哪了？）

楼主是在本机上写的Client 和 Server两个类？如果是在本地机上，你的ip地址应该是127.0.0.1啊，或者是你本地机的ip，可以在控制台下输入ipconfig来查看你当前的ip地址。
