TCP写的一个点对点的聊天程序练习，可是总是有问题，连接上不能输入，求大神帮助
程序代码：/**
* @author 小南
* 客户端
*/
import *;
import *;
public class TCPClient {
public static void main(String args[]) throws Exception{
Socket s = new Socket("172.0.0.1",5003);
System.out.println("client connect is ok");
Thread.sleep(2000);
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
BufferedReader netin = new BufferedReader(new InputStreamReader(s.getInputStream()));
BufferedWriter netou = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
String rd = null;
rd = br.readLine();
while(rd!="bye") {
netou.write(rd);
netou.flush();
System.out.println("Server:" + netin.readLine());
rd = br.readLine();
}
br.close();
netin.close();
netou.close();
s.close();
}
}
这里是服务器端程序代码：/**
* @author 小南
* 服务器端
*/
import *;
import *;
public class TCPServer {
public static void main(String args[]) throws Exception{
ServerSocket ss= new ServerSocket(5003);
Socket s = new Socket();
s = ss.accept();
Thread.sleep(2000);
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
BufferedReader netin = new BufferedReader(new InputStreamReader(s.getInputStream()));
BufferedWriter netou = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
String rd = null;
rd = br.readLine();
while(rd!="bye") {
netou.write(rd);
netou.flush();
System.out.println("Client:" + netin.readLine());
rd = br.readLine();
}
br.close();
netin.close();
netou.close();
s.close();
ss.close();
}
}
连接正常，但是不能通话，实在找不到问题，求大神解决
