Asynchronous programming is what the CompletionStage API, from the JDK, brings you. This course covers all the patterns you need to create efficient asynchronous data processing pipelines, including thread control and error recovery.

As a Java developer, being able to create asynchronous systems allows you to develop very efficient applications, that need both throughput and performance. In this course, Java 8 Fundamentals: Asynchronous Programming Using CompletionStage, you will learn all the patterns brought to you by this API. First, you will learn the concepts of asynchronous programming: tasks, non-blocking calls and multi-threaded systems. Then, you will see how to build data processing pipelines where the completion of a first task automatically triggers the execution of a next task, passing data to it. Finally, you will see how to create performant systems by controlling the execution of each task in the right thread. Mastering all of this will help you in creating performant and error-free asynchronous systems with the only dependency being the JDK itself.

Reviews summary

Java 8 asynchronous programming fundamentals

According to students, this course provides an exceptionally clear and concise overview of Java 8's CompletionStage API, making asynchronous programming concepts much easier to grasp. Learners frequently highlight the instructor's knowledgeable and engaging approach, praising the effective hands-on demos and practical examples that help solidify understanding. While the lectures are largely positive, some note the pace can be slow or that it assumes a foundational understanding of threading. Despite minor critiques regarding depth on more advanced scenarios, it is widely regarded as a solid and highly relevant foundation for professional Java developers aiming to build performant and efficient applications.
Instructor is highly regarded for expertise and effective teaching.
"The instructor's explanations are incredibly clear..."
"The instructor is knowledgeable and presents the material in an engaging way."
"Solid introduction to CompletionStage. The instructor knows his stuff."
"The instructor is clear and provides good examples."
Hands-on demonstrations effectively solidify theoretical concepts.
"...the hands-on demos truly solidify the concepts. I've been struggling with async Java for a while, and this course finally made it click."
"I appreciated the practical examples, though I wish there were more advanced use cases or a dedicated module on integrating with other reactive libraries..."
"I especially liked the practical demos which made it easy to follow along and try out the code myself. My code quality for async operations has definitely improved."
"I feel much more confident building performant applications now."
Complex asynchronous concepts are explained with exceptional clarity.
"Absolutely brilliant! This course demystifies CompletionStage. The instructor's explanations are incredibly clear, and the hands-on demos truly solidify the concepts..."
"A concise and effective dive into Java 8's CompletionStage. The content is well-structured, building from basics to more complex scenarios..."
"This course is a gem for understanding CompletionStage! The way the instructor broke down complex topics into digestible parts was amazing."
"Absolutely fantastic! The explanations are crystal clear, and the practical examples reinforce the concepts beautifully."
Some desire more advanced topics or broader real-world applications.
"I wish there were more advanced use cases or a dedicated module on integrating with other reactive libraries like RxJava or Project Reactor for a more complete picture."
"Sometimes I felt the explanations were a bit too theoretical without enough real-world application."
"While it covers the API, it often feels like just an API tour rather than teaching the 'why' behind asynchronous patterns. The exercises were minimal..."
"My only minor critique is that it could benefit from more detailed discussions on debugging async code, which can be tricky."
Better suited for those with some prior threading knowledge.
"For a 'fundamentals' course, it assumes a bit too much prior knowledge of asynchronous concepts. I had to look up some things outside the course."
"If you're a complete beginner to concurrent programming, you might find it challenging."
"It's best suited for developers with some basic understanding of threading."
"I would recommend it for those who are already comfortable with Java 8 features."
