Java Fundamentals: HttpClient

Course Overview
Hi everyone. My name is Sander Mak, and welcome to my course Java Fundamentals: HttpClient. I'm a fellow and software architect at Luminous in the Netherlands and author of the O'Reilly book Java 9 Modularity. It used to be that performing HTTP calls in Java meant using an external library such as Apache HttpClient or OkHttp. That changed after an all new HttpClient was introduced in Java 11. Now, a modern and full-featured HttpClient is part of the core Java platform. Recent standards, such as HTTP/2 and WebSocket, are fully supported. Whenever you need to perform HTTP calls, you should reach for this HttpClient API. In this course, we'll look at the basic features of HttpClient, as well as explore some of its more advanced features. Through both explanations and hands-on examples, you'll learn how the API works and what it can do. Among other things, the following topics are covered. We'll start with the basics by looking at how we can perform HTTP requests, and we'll dive into both a synchronous blocking API, as well as the asynchronous and non-blocking API that's part of HttpClient. We'll also see how HttpClient supports secure communication. And finally, we'll explore some more advanced features like support for HTTP/2 Server Push, WebSocket, and integration with Reactive Streams. This course assumes you have experience with Java development and that you have a general knowledge of the HTTP protocol itself. After finishing this course, you'll know enough about the HttpClient API to start using it predictably in your own code. I hope you'll join me on this journey to start learning about Java's HttpClient API with the Java Fundamentals: HttpClient course, here at Pluralsight.
