The HttpURLConnection is the oldest implementation of an HTTP client in Java and is still widely used today due to its simplicity and the fact that it is very lightweight. Use this course to familiarize yourself with different forms of HTTP requests.
Try your hand at constructing a basic GET request to retrieve data, submitting it to a remote server, and processing the response that is returned. You'll also examine the use of a POST request to submit data to create a resource at a server, a PUT request to update a resource, and a DELETE request to remove it. You'll also look into setting a timeout for requests that take too long to process.
After finishing this course, you'll be able to identify various HTTP requests and how these can be formulated and communicated in a Java app using the HttpURLConnection class.
