How to Execute an HTTP GET Request in Java and Retrieve Response Code and Body

In a rapidly evolving digital landscape, making HTTP GET requests and processing the responses is a fundamental requirement. Java provides several libraries to facilitate these operations, making it easier for developers to connect and interact with web services. This blog will guide you through the process of executing an HTTP GET request using Java and how to retrieve both the response code and the response body.

Using Java's HttpURLConnection

Java's standard library includes HttpURLConnection, which is a robust and straightforward choice for handling HTTP requests.

Here's an example to demonstrate how to execute an HTTP GET request using HttpURLConnection:
