不能获取服务端第二次发送的信息（SOCKET）,请代码注释处。

Question

import java.io.*;
import java.net.*;public class JavaClient {
    Socket socket;
    BufferedReader in;
    PrintWriter out;
    DatagramSocket socket1;    public static void main(String[] args) {
        JavaClient client = new JavaClient();
    }    public JavaClient() {
        test();
    }    private void test() {
        try {
            socket = new Socket("192.168.5.1", 6789);
            in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
            out = new PrintWriter(socket.getOutputStream(), true);            out.write("CONN|wxl");
            out.flush();
            System.out.println(in.readLine());
            
            out.write("CHAT|wxl");
            out.flush();
            System.out.println(in.readLine());//程序在这获取不到服务端发送过来的信息，在此运行不下去，不知道怎么回事？
            
            
            out.close();
            in.close();
            socket.close();
        } catch (IOException e) {
            e.printStackTrace();
        }    }
