javaSocket网络编程

大家好，又见面了，我是你们的朋友全栈君。

昨天和今天了解了一下这个网络编程；

服务端

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

public class TestServer { 
   
    public static void main(String args[])throws Exception{ 
   
        ServerSocket ss = new ServerSocket(6666);
        while (true) { 
   
            Socket s = ss.accept();
            System.out.println("A Client connect");
            DataInputStream dis = new DataInputStream(s.getInputStream());
            System.out.println(dis.readUTF());
            dis.close();
            s.close();
        }
    }
}

客户端

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

public class TestClient { 
   
    public static void main(String args[])throws  Exception{ 
   
        Socket s = new  Socket("127.0.0.1",6666);
        OutputStream os = s.getOutputStream();
        DataOutputStream dos = new DataOutputStream(os);
        Thread.sleep(3000);
        dos.writeUTF("hello server");
        dos.flush();
        dos.close();
        s.close();


    }
}

运行结果
TestServer:

A Client connect
hello server
