服务器端程序：
import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.ServerSocket;
import java.net.Socket;

public class server {
static Socket socket;
public static void main(String args[]){

try {
ServerSocket ss=new ServerSocket(3342);
System.out.println("Connecting...");
while(true){
socket=ss.accept();
System.out.println("Connected");
BufferedReader reader=new BufferedReader(new InputStreamReader(socket.getInputStream()));
System.out.println(reader.readLine()+"haode");

PrintWriter writer=new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())));
writer.write("wwwwwwwwwwwwwww");
writer.flush();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
}
问题：运行程序时，服务器端只打印出
Connecting...
Connected
后面的语句System.out.println(reader.readLine()+"haode");没有打印出任何东西；
但是去掉红色字体部分就能够在服务器打印出接受到的来自客户端的信息，只是要点击两次按钮
求正解...
