JAVA -------- Create a TCP service to pass data

Not much to say, directly upload the code, start the server first when running, and then start the client

client:

import java.awt.Container; 
import java.awt.event.ActionEvent; 
import java.awt.event.ActionListener; 
import java.io.*; 
import java.net.Socket; 
import java.net .UnknownHostException; 
import java.nio.channels.WritableByteChannel; 

import javax.swing.JFrame; 
import javax.swing.JScrollPane; 
import javax.swing.JTextArea; import 
javax.swing.JTextField 
; 

public class Tcp_Client{ 
    public static void main(String[] args) { 

        try { 

//Create a client socket 

            Socket socket = new Socket("localhost",8888); 
         
//Transfer information to the server

            OutputStream ots = socket.getOutputStream(); 

            PrintWriter pw = new PrintWriter(ots); 

            pw.write("111222123"); 

            pw.flush(); 

//Close the output stream 

            socket.shutdownOutput(); 

//Get the server-side delivery The data 

            InputStream is = socket.getInputStream(); 

            InputStreamReader isr = new InputStreamReader(is,"UTF-8"); 

            BufferedReader br = new BufferedReader(isr); 

            String info = null; 

            while((info=br.readLine() )!=null){ 

                System.out.println("I am the client, the server said: "+info); 

            } 

//Close the resource 

            br.close(); 

            isr.close();

            is.close();

            pw.close();

            ots.close();

            socket.close();

        } catch (UnknownHostException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        }

    }

}
