Java Concurrency in Practice. Brian Goetz with. Tim Peierls. Joshua Bloch. Joseph Bowbeer. David Holmes and Doug Lea. Upper Saddle River, NJ • Boston . With Java 9 and 10,we got more new java versions over the last few months than we had over the last 5 years, so you can work on the book, and, while at it, you. Yes, it’s still valid in my mind. There isn’t big change in this area from 6 to 7. Fork- join is a new feature, which is very suitable for divide-and-conquer type of.

Java Concurrency in Practice [Book]
This books gives you lots of information in a single easy place to find, so I’ll delve immediately into describing what can you learn from it.
On conccurrency processor architectures, multithreading and concurrency have in general become a small distributed system inside a motherboard, spanning the centimeters that separate the CPU cores and the RAM.
In fact, you can see many parallels between the two field: CPUs are different machines, and coordinating between them is relatively more costly than allowing independent executions.
The L1, L2, and L3 caches near the CPU cores behave as replicas, showing tunable consistency models and forcing compilers to introduce synchronization where needed. Moreover, partial failure is always around the corner concurency threads run independently.
Is “Java Concurrency In Practice” still valid? – Stack Overflow
Forcing programmers to deal with possible failure is one of the few usages of checked exceptions that I find not only acceptable but also desirable. I tend not to like checked exceptions too much as they tend to be replicated in too many places in the code, creating coupling.
The book is ripe with Java Virtual Machine concurrency concepts, building a pattern language for talking about thread safety and performance which are the goals we are pursuing with concurrent applications. Java’s model is based on multithreading and shared memory, where the virtual threads are mapped 1: Basic concepts are necessary for understanding what’s going on in your VM, but they are an insufficient level of abstraction for productive work. For this reason, the book explains the usage of several standard libraries:.
Thus, part of the book has an emphasis of using the best tools available in Java SE instead of reinventing the wheel with Object. Reinventing the wheel can be an error-prone task that produces inferior results, and it should not be the only option just because it’s the only approach you know.
You will still need to integrate this knowledge with Java 8 parallel streams. It takes focus to get through this book, and I spent several dozen hours to read the 16 chapters.
The annotations such as GuardedBy won’t compile if you don’t download a separate package; it’s too bad they’re not a standard since the authors are luminaries of the Java concurrency field, experts from many JSR groups and Java programming language authors.
You probably will need some review on the most difficult topics, just to hear brain as explained from different people. Stack Overflow conxurrency many blog articles will be your friend as you look for examples of unsafe publication or of the Java Memory Model.
Book Review: ‘Java Concurrency in Practice’
I’m a fan of getting to the bottom of how things do work and don’t. I would definitely recommend this book if you are executing your code in multiple threads, as sooner or later you will be bitten without even understanding what went wrong.
Even if you’re just writing a Servlet, that code could become a target for concurrency. Moreover, as for distributed systems, in concurrency simple testing is not enough: You need theory, code review, static analysis: Get the open source Atomist Software Delivery Machine and start automating your delivery right there on your own laptop, today!

Relevant JVM Topics The book is ripe with Java Virtual Machine concurrency concepts, building a pattern language for talking about thread safety and performance which are the goals we are pursuing with concurrent applications. These are not generic terms but are really concrete, explained with many code samples. Libraries Basic concepts are necessary for understanding what’s going on in your VM, but they are an insufficient level of abstraction for productive work.
For this reason, the book explains the usage of several standard libraries: Creating threads by hand is a beginner’s solution.
