This course covers some of the fundamentals and inner workings of the Java Virtual Machine. This class will be the first in the series and will examine class loading.
Java is built around classes; these classes have to be loaded into memory and loading that is the responsibility of class loaders. The first part of this course will look at this class loading mechanism and how to write class loaders. Once you understand this, several scenarios become available, such as hot deployment of classes and the side-by-side loading of classes. Java has a rich type system and rich metadata. Reflection is the mechanism by which you can examine that metadata at runtime, and use that information to build rich applications. In the second part of this course, we will see how to use reflection to both examine this metadata at runtime and use it within our applications.

Reviews summary
Jvm internals: class loading & reflection
According to learners, this course offers an excellent deep dive into the inner workings of the Java Virtual Machine, particularly in class loading and reflection. Students frequently highlight the instructor's clear explanations of complex concepts and the value of practical examples, especially the hands-on activity of building an IoC container. While considered highly relevant for professionals seeking to understand 'magic' behind the scenes, prospective students should note it is not for beginners and may have a fast pace, occasionally requiring self-study for deeper grasp of intricate topics.
Strong emphasis on hands-on application and demos.
"Building the IoC container was the highlight, truly demonstrating the power of reflection."
"I appreciated the hands-on coding examples and the build-up to the IoC container."
"I especially appreciated the hands-on examples that accompanied each concept, reinforcing the learning."
Instructor excels at explaining complex topics clearly.
"The instructor's explanation of class loading, especially custom class loaders and hot deployment, was incredibly clear and practical."
"The instructor clearly knows his stuff."
"The instructor's ability to simplify complex topics is remarkable."
Provides a thorough understanding of core JVM concepts.
"This course is absolutely fantastic for anyone looking to dive deep into JVM internals."
"Excellent deep dive into an often-overlooked area of Java."
"This course genuinely filled gaps in my understanding of how Java applications truly work under the hood."
Pace can be fast, some desire more complex scenarios.
"My only minor critique is that some parts felt a bit rushed, and I occasionally wished for more advanced real-world scenarios."
"I found the pace quite fast at times, assuming a significant prior understanding of intricate Java concepts."
"I would have loved even more complex scenarios or troubleshooting tips for real-world issues..."
Best suited for intermediate to advanced Java developers.
"Highly recommend for intermediate to advanced Java developers."
"This course is definitely for those who already have a strong grasp of Java basics and want to understand the 'magic' behind the scenes. It's not for beginners."
"If you're not already comfortable with advanced Java, be prepared for a steep learning curve."
