Networkingclass1

Overview

This is a simple Java application that demonstrates how to make an HTTP GET request to a REST API endpoint using Java's HttpURLConnection. The application fetches data from https://jsonplaceholder.typicode.com/posts, prints the response code and message, and displays the retrieved JSON data.

Features

• Establishes an HTTP connection to a given URL
• Sends a GET request with a custom User-Agent header
• Reads and prints the response status code and message
• Fetches and displays the full response data from the API

Prerequisites

To run this project, ensure you have the following installed:

• Java Development Kit (JDK) 8 or later

How to Run

1. Clone or download the project files.
2. Open a terminal or command prompt in the project directory.
3. Compile the Java program:

   javac Networkingclass1.java

4. Run the compiled class:

   java com.mycompany.networkingclass1.Networkingclass1

Expected Output

When executed, the program should display:

• HTTP response code (e.g., 200 for success)
• HTTP response message (e.g., OK)
• The retrieved JSON response data from the API

Notes

• The API used (https://jsonplaceholder.typicode.com/posts) is a free fake online REST API for testing and prototyping.
• The response is printed as a single string; formatting may be necessary for better readability.
