Reviews summary

Java 9 features: clear and concise overview

According to learners, this course offers a largely positive and concise overview of Java 9's new features, making it suitable for professionals updating their skills. Students praise its clarity in explaining complex topics, particularly the Java Platform Module System and the utility of JShell, alongside improvements to Stream and Optional APIs. The instructor's knowledge and the directness of the lectures are frequently highlighted. However, some learners desired more hands-on coding exercises and deeper, real-world examples. A significant point raised in recent reviews is the timeliness of Java 9 itself, suggesting the course content may be outdated for current Java development environments.

Ideal for busy professionals seeking a quick and efficient update.

"Very concise and to the point, which is perfect for busy professionals."

"I completed it quickly and feel confident with Java 9 now."

"The pace is generally good."

Provides excellent and clear explanations for challenging concepts.

"The explanation of the module system (Jigsaw) was incredibly clear, which is a notoriously complex topic."

"The module system was demystified for me."

"The instructor makes complex topics like the HTTP/2 API easy to understand."

Could benefit from more practical coding exercises and real-world examples.

"I would have liked more hands-on coding exercises, especially for the HTTP/2 API."

"The module system still feels a bit abstract without more real-world project examples to follow along with."

"It's more of a 'here's what's new' rather than 'here's how to deeply use it'."

While high quality, the Java 9 focus may be outdated for current development.

"Focusing solely on Java 9 in 2022 feels a bit outdated when Java 17 LTS is widely used."

"I wish it were updated to include more recent Java features, or perhaps re-framed as a historical overview."

"The course quality is decent for what it covers, but its relevance for current projects is questionable."
