Java Fundamentals: HttpClient from Pluralsight

With Java's HttpClient API you can easily perform HTTP calls. It's a modern API supporting HTTP/1.1, HTTP/2, and WebSockets. This course shows how to work with HttpClient in a practical manner, and also explores some advanced features.

It used to be that performing HTTP calls in Java meant relying on an external library like Apache HttpClient. Since Java 11, a modern HTTP client is now part of the core platform. In this course, Java Fundamentals: HttpClient, you will gain the ability to work with this HttpClient API. First, you will learn to use HttpClient in a synchronous and asynchronous manner, including the use of CompletableFuture. Next, you will discover how to configure and use HttpClient in different scenarios, focusing on secure communication as well. Finally, you will explore some of the more advanced features of HttpClient, such as HTTP/2 Server Push, WebSocket communication, and Reactive Streams integration. When you're finished with this course, you will have the skills and knowledge of the HttpClient API needed to use it effectively in your own applications.

Reviews summary

Java httpclient: modern api essentials

According to learners, this course offers a solid and highly practical introduction to Java's native HttpClient API, making it an essential resource for modern Java development. Students frequently highlight the clarity of explanations and the effectiveness of hands-on demonstrations, which simplify complex topics like CompletableFuture and HTTP/2. Many found it particularly valuable for upgrading skills from older HTTP client libraries. While largely receiving positive feedback, a few reviews noted that the pace might be quick for those new to asynchronous programming, and some expressed a desire for more extensive coverage of advanced enterprise-level scenarios. Overall, it is considered a highly valuable and current guide for Java developers.

Assumes prior Java knowledge, best for existing developers.

"It's definitely for developers who already know Java."

"This will be very useful in my professional work. Highly recommend for Java developers."

"Maybe better for intermediate Java devs rather than complete beginners to programming."

Explores advanced topics such as HTTP/2 Server Push and WebSockets.

"I especially appreciated the coverage of HTTP/2. This will be very useful in my professional work."

"It covers the basics well and touches on advanced topics. I liked how it moved into Reactive Streams integration."

"I found the WebSocket part a bit rushed, but overall solid coverage of advanced features."

Focuses on Java's native HttpClient, crucial for modern development.

"A must-have for modern Java development. It's great to see a course dedicated to the native HttpClient."

"Perfect for upgrading my skills from Apache HttpClient."

"I found this very useful in my professional work, especially learning about the new features of Java 11+."

Provides clear explanations with highly practical, hands-on examples.

"Excellent course! The instructor explained complex concepts like CompletableFuture very clearly. I especially appreciated the hands-on demos."

"The examples were practical and directly applicable. I liked how it moved from basic usage to more advanced patterns... Clear and concise."

"The explanations were clear, and the code examples were helpful. Good for a quick grasp of HttpClient."

Pacing may be fast for some; some desire more in-depth coverage.

"The course is okay, but I felt it moved a bit too fast in some areas, especially for someone new to async programming."

"I wish there was more depth on error handling and retries. Still, it's a very practical course for integration."

"I was expecting more advanced use cases and performance tuning tips. It felt too 'fundamental' for my needs as an expert."
