服务器端代码：

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

public class MyServer {
    public static void main(String[] args) throws IOException {
        ServerSocket server = new ServerSocket(5678);
        Socket client = server.accept();
        BufferedReader in = new BufferedReader(new InputStreamReader(client.getInputStream()));
        PrintWriter out = new PrintWriter(client.getOutputStream());
        
        while(true) {
            String str = in.readLine();
            System.out.println(str);
            out.println("has receive...");
            out.flush();
            if(str.equals("end"))
                break;
        }

    }
}

客户端代码：

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

public class Client {
    static Socket server;
    
    public static void main(String[] args) throws Exception {
        server = new Socket(InetAddress.getLocalHost(), 5678);

        BufferedReader in = new BufferedReader(new InputStreamReader(server.getInputStream()));
        PrintWriter out = new PrintWriter(server.getOutputStream());
        BufferedReader wt = new BufferedReader(new InputStreamReader(System.in));

        while(true) {
            String str = wt.readLine();
            out.println(str);
            out.flush();

            if(str.equals("end")) {
                break;
            }

            System.out.println(in.readLine());
        }

        server.close();
    }
}
