Reactive Programming in Java 12 with RxJava 2

Russell Elledge

In this course you will learn to use the RxJava Version 2 library to accomplish the goals of the Reactive Manifesto, the software industries standard for Reactive Programming.

Due to heat limitations, modern computer systems have been unable to increase CPU clock speeds in order to increase chip performance. Instead, chip designers have begun to scale performance using an increasing number of on-chip processor cores.

In this course you will learn to use the RxJava Version 2 library to accomplish the goals of the Reactive Manifesto, the software industries standard for Reactive Programming.

Due to heat limitations, modern computer systems have been unable to increase CPU clock speeds in order to increase chip performance. Instead, chip designers have begun to scale performance using an increasing number of on-chip processor cores.

In this course, Reactive Programming in Java 12 with RxJava 2, you will gain the ability to implement Reactive Programming techniques in order to more fully utilize a modern computer's multi-core CPU.

First, you will learn The Reactive Manifesto, the software industries de facto standard for Reactive Programming. Next, you will discover how the RxJava library can be leveraged to tame the difficult task of implementing asynchronous applications. Finally, you will explore how to apply Reactive Programming to modern day problems like network and database access.

When you’re finished with this course, you will have the skills and knowledge of Reactive Programming and the RxJava library needed to implement applications and services that exhibit the quality standard laid out in the Reactive Manifesto.

Reviews summary

Practical reactive programming with rxjava 2

According to students, this course offers a largely positive and thorough introduction to Reactive Programming with RxJava 2 in Java 12. Learners consistently praise the instructor's clear and concise explanations of complex topics, along with the highly practical hands-on coding exercises and real-world examples, making the concepts directly applicable. While many find the pacing just right and the content easy to follow, some indicate that it might assume a level of prior knowledge in asynchronous or functional programming, potentially making it challenging for absolute beginners in those areas. Overall, it provides a solid foundation for implementing reactive patterns.
Provides a comprehensive and solid foundation in RxJava 2.
"A very solid introduction to RxJava 2. The course covers the Reactive Manifesto well and then transitions smoothly into RxJava concepts."
"Excellent course! As an experienced Java developer, I was looking for a concise yet thorough guide to RxJava, and this delivered."
"Phenomenal! This course covers everything you need to get started with Reactive Programming in Java."
Instructor delivers complex concepts with clarity and practical examples.
"The instructor's explanations are incredibly clear and concise, breaking down complex topics into digestible chunks."
"The instructor has a great way of explaining difficult concepts simply, and the practical application examples are top-notch."
"Every topic was explained thoroughly, and the hands-on labs reinforced the concepts effectively."
Focuses on real-world scenarios, making concepts directly applicable.
"I particularly appreciated the hands-on coding exercises and the real-world examples, which really helped solidify my understanding."
"It truly helped me understand how to leverage multi-core systems effectively using reactive principles."
"The progression from basic concepts to complex scenarios like network calls and database access was logical and easy to follow."
"I've already started applying these patterns in my projects."
Suggestions for more challenging exercises and debugging focus.
"Good course, though I wished there were more challenging exercises."
"I think a bit more emphasis on debugging reactive streams would be beneficial."
"The code examples were helpful, but sometimes lacked enough commentary to fully grasp the 'why' behind certain choices."
Pacing may be fast for some; some prior async knowledge is helpful.
"Some concepts felt rushed, especially in the later modules. While the core RxJava concepts were covered, I felt it assumed a bit too much prior knowledge..."
"I found this course somewhat difficult to follow. The explanations were not always clear for someone without a strong background in functional programming."
"The content is mostly good but the delivery could be improved. I felt the pacing was inconsistent, sometimes too fast, sometimes too slow."
"My only minor critique is that sometimes the demos felt a bit too quick, and I had to pause frequently to follow along."
