TCP 客户端在 JAVA 后未响应

Question

我正在学习 JAVA 网络 API 和简单的 TCP 服务器-客户端通信。我为客户端和服务器写了以下两个类。问题是我的客户端没有响应，即程序没有终止，也没有输出任何东西。谁能看出我哪里出错了？

客户：

import java.io.*;
import java.net.*;

public class client {

    public void go() {
        try {
            Socket s = new Socket("127.0.0.1",2323);

 InputStreamReader streamReader = new InputStreamReader(s.getInputStream());
            BufferedReader reader = new BufferedReader(streamReader);
            String reading = reader.readLine();


            PrintWriter write = new PrintWriter(s.getOutputStream());
            write.print("mynameistom");

           

            System.out.println(reading);


            reader.close();
            writeToServer.close();
        } catch(IOException ex) {
            ex.printStackTrace();
        }
    }
    public static void main(String[] args) {
        Client client = new Client;
        client.go();
    }
}

服务器：

package TCP;

import java.io.*;
import java.net.*;
public class Server {

        public void go() {
        try {
        ServerSocket serverSock = new ServerSocket(2323);


        Socket socket = serverSock.accept();
           
                InputStreamReader streamReader = new InputStreamReader(socket.getInputStream());
                BufferedReader reader = new BufferedReader(streamReader);
                String messsage = reader.readLine();
              
        PrintWriter writer = new PrintWriter(socket.getOutputStream())

        writer.println(message);
        writer.close();
        System.out.println(message);

        } catch(IOException ex) {
        ex.printStackTrace();
        }
        }



public static void main(String[] args) {
        Server server = new Server();
        server.go();
        }
        }

很明显，客户端没有刷新，并且缺少新行。

        PrintWriter writeToServer = new PrintWriter(s.getOutputStream());
        writeToServer.print("network");

应该是

        PrintWriter writeToServer = new PrintWriter(s.getOutputStream(), true);
        writeToServer.println("network");

或

        PrintWriter writeToServer = new PrintWriter(s.getOutputStream());
        writeToServer.println("network");
        writeToServer.flush();
