If you need some help and want to see things, in reality, I also suggest you check out the Java Application Performance and Memory Management course by Matt Greecroft and Virtual Programmers. algorithms in-depth but may not be needed for most of the developers. This book is also much more approachable in this list than some specialized books like The Garbage collection handbook, which is excellent for people who want to learn G.C. Moreover, the book contains an overview of many useful tools that can help you on a daily basis work with JVM. Many books focus mainly on G.C., but this one describes many more aspects of JVM internals like threading, JVM internal memory representation, bytecode, JIT compilers, etc. I originally missed this book on the list because I haven't read it until Ben suggested it in the comments, but just reading a couple of pages, I was convinced that this book deserves mention in this list. The Optimizing Java: Practical Techniques for Improving JVM Application Performance 1st Editionīy Benjamin J Evans, James Gough, and Chris Newland is one of the best books to understand how Garbage collection and JVM works internally. Once you have good knowledge, you can check other books to learn more about them. Though you don't need to read all the books to become an expert in JVM internals, you choose the one book along with the specification and stick with it. Without wasting any more of your time, here is my list of some of the best books to learn JVM internals, Garbage Collection, and Performance tuning in Java. It's not for beginners, and most likely lot of concepts will go top of your head unless you understand critical components like JIT, Garbage collector, Java heap structure, byte codes, and other JVM internals.ītw, if you prefer online courses, which I do nowadays, I also suggest you check the Understanding the Java Virtual Machine series of courses on Pluralsight, which covers memory management, Security, and Class Loading and Reflection.Ħ Best JVM Internals and Java Performance Books for Experienced Developers The books in this list are solely for advanced Java developer who has at least 4 to 6 years of Java working experience under their belt. I receive a lot of emails about the recommendation of the best books to learn JVM internals and garbage collections from experienced Java programmers, and hence I decided to write about this post to share some of the best books on JVM internals and Java performance, Garbage collection, and memory management in general. Once you know the fundamentals, you can easily apply the more advanced concepts. It is also the most up-to-date reference because Java and JVM are kept changing, especially after Java 10. Unfortunately, there are not many good books to learn about JVM internals and their different components, but fortunately, we have an excellent Java Virtual Machine specification to learn fundamentals. This trend was not so strong in the last decade, but with more and more focus on concurrency, performance, and scalability, Java developer is exploring JVM internals, Garbage collection, and Performance tuning in more detail. In the last couple of years, I have seen a trend of many Java developers wants to learn more and more about JVM internals and how Java Virtual Machine and its different component works.
