How Can Java.net.urlconnection Be Used To Initiate And Manage HTTP Requests In Java?

To use java.net.URLConnection to fire and handle HTTP requests, you can follow these steps:

Step 1: Create a URL object

URL url = new URL("http://www.example.com");

Step 2: Open a connection using the URL object

URLConnection connection = url.openConnection();

Step 3: Set up the properties of the connection, such as request method, headers, and timeouts

connection.setRequestMethod("GET");
connection.setRequestProperty("User-Agent", "Mozilla/5.0");

connection.setConnectTimeout(5000); // 5 seconds
connection.setReadTimeout(5000); // 5 seconds

Step 4: Connect to the remote server

connection.connect();

Step 5: Read the response from the server

InputStream inputStream = connection.getInputStream();

BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line;
StringBuilder response = new StringBuilder();

while ((line = reader.readLine()) != null) {
    response.append(line);
}

reader.close();

Step 6: Handle the response

System.out.println(response.toString());

Step 7: Handle any exceptions that might occur during the process

catch (MalformedURLException ex) {
    ex.printStackTrace();
} catch (IOException ex) {
    ex.printStackTrace();
}

Note: This is just a basic example. Depending on your specific use case, you may need to handle redirects, set request parameters, handle different HTTP methods, handle response codes, etc.
