求教一个关于客户端与服务器端交互的问题

[yskshr]

客户端
public class Client {
public static void main(String[] args) throws UnknownHostException, IOException {
Socket s=new Socket("LocalHost",8888);
PrintWriter out=new PrintWriter(s.getOutputStream());
out.write("ni hao");
out.flush();
BufferedReader in=new BufferedReader(new InputStreamReader(s.getInputStream()));
System.out.println(in.readLine());//这里会一直为阻塞状态
out.close();
}
}
服务器端
public class Server {
public static void main(String[] args) throws IOException {
Socket s=null;
ServerSocket ss=new ServerSocket(8888);
s=ss.accept();
BufferedReader in=new BufferedReader(new InputStreamReader(s.getInputStream()));
System.out.println(in.readLine())];
//这里也为阻塞状态，如果将客户端的out.close();写到客户端的in.readLine()
前又会报Exception in thread "main" java.net.SocketException: Socket is closed at java.net.Socket.getInputStream(Unknown Source)错误，求解决方法
PrintWriter pw=new PrintWriter(s.getOutputStream());
pw.write("hello");
pw.flush();
pw.close();
}
}

readLine 需要读到换行符才能返回，所以需要加个换行符 "\n"。

在客户端client的out.flush后面加上 out.shutdownOutput

多谢，多谢，问题解决了。
