Creating a Simple HTTP Server with Java

Hey everyone! 👋 Today, I want to share a quick guide on how to create a simple HTTP server in Java using the ServerSocket class. This is a great way to understand the fundamentals of networking in Java.

Here’s a brief overview of how it works:

1. Setup a ServerSocket: This will allow your server to listen for incoming connections.
2. Accept Client Connections: The server waits and accepts client requests.
3. Handle Requests: Read the input from the client, generate a response, and send it back.

Here's a basic code snippet to get you started:

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

public class SimpleHttpServer {
public static void main(String[] args) throws IOException {
ServerSocket serverSocket = new ServerSocket(8080);
while (true) {
Socket clientSocket = serverSocket.accept();
handleRequest(clientSocket);
}
}

private static void handleRequest(Socket clientSocket) throws IOException {
BufferedReader in = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
PrintWriter out = new PrintWriter(clientSocket.getOutputStream(), true);

String requestLine = in.readLine();
// Just for demo purposes, send back a simple HTTP response
out.println("HTTP/1.1 200 OK");
out.println("Content-Type: text/plain");
out.println();
out.println("Hello, World!");

clientSocket.close();
}
}


Key Points to Remember:
- The server listens on port 8080.
- You can customize the response based on the request.

Give it a try and let me know how it goes! Happy coding! 🚀

What is Telegram?

Telegram is a cloud-based instant messaging service that has been making rounds as a popular option for those who wish to keep their messages secure. Telegram boasts a collection of different features, but it’s best known for its ability to secure messages and media by encrypting them during transit; this prevents third-parties from snooping on messages easily. Let’s take a look at what Telegram can do and why you might want to use it.

However, analysts are positive on the stock now. “We have seen a huge downside movement in the stock due to the central electricity regulatory commission’s (CERC) order that seems to be negative from 2014-15 onwards but we cannot take a linear negative view on the stock and further downside movement on the stock is unlikely. Currently stock is underpriced. Investors can bet on it for a longer horizon," said Vivek Gupta, director research at CapitalVia Global Research.
