how to run a program of socket programming in VS code with java |short video|

in this vedio we see how to run program of socket programming in VS code with java programming language.

socket programming : Socket programming involves two main components: a client and a server a client can send a message to the server, and the server can receive and send a response back to the client,


code for client.java file

//client

import java.io.OutputStreamWriter;
import java.io.PrintWriter;
import java.net.Socket;

public class client{
public static void main(String[] args) throws Exception {
String ip = "localhost";
int port = 9999;
Socket s = new Socket(ip, port);

String str = "socket pro";

OutputStreamWriter os = new OutputStreamWriter(s.getOutputStream());
//PrintWriter out = new PrintWriter(os);

os.write(str);
os.flush();

s.close();
}
}




code for server.java file

//server

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class server {
public static void main(String[] args)throws Exception {

System.out.println("server is started");
ServerSocket ss = new ServerSocket(9999);

System.out.println("server is waiting for client request");
Socket s = ss.accept();
System.out.println("client connected");

BufferedReader br = new BufferedReader(new InputStreamReader(s.getInputStream()));
String str = br.readLine();

System.out.println("client data : " + str);

ss.close();
s.close();
}
}
