Java Concurrency in Practice. Brian Goetz with. Tim Peierls. Joshua Bloch. Joseph Bowbeer. David Holmes and Doug Lea. Upper Saddle River, NJ • Boston . „A class is thread-safe if it behaves correctly when accessed from multiple threads, regardless of the scheduling or interleaving of the execution of those. 2 Concurrency Fundamentals: Deadlocks and Object Monitors. 11 .. Java Concurrency Essentials. 4 / 52 practice. Hence you should not use this method for.
Concurrent Programming - Spring 2018
Chapter 6 Task Execution covers identifying parallelizable tasks and executing them within the task-execution framework. Chapter 7 Cancellation and Shutdown deals with techniques for convincing tasks and threads to terminate before they would normally do so; how programs deal with cancellation and shutdown is often one of the factors that separates truly robust concurrent applications from those that merely work.
Chapter 8 Applying Thread Pools addresses some of the more advanced features of the task-execution framework. Chapter 9 GUI Applications focuses on techniques for improving responsivenessin single-threaded subsystems.

Liveness, Performance, and Testing. Part III Chapters concerns itself with ensuring that concurrent programs actually do what you want them to do and do so with acceptable performance. Chapter 10 Avoiding Liveness Hazards describes how to avoid liveness failures that can prevent programs from making forward progress.
Chapter 11 Performance and Scalability covers techniques for improving the performance and scalability of concurrent code. Chapter 12 Testing Concurrent Programs covers techniques for testing concurrent code for both correctness and performance. Advanced Topics.
Part IV Chapters covers topics that are likely to be of interest only to experienced developers: explicit locks, atomic variables, nonblocking algorithms, and developing custom synchronizers. Code examples While many of the general concepts in this book are applicable to versions of Java prior to Java 5.
Some of the code examples may use library features added in Java 6. The code examples have been compressed to reduce their size and to highlight the relevant portions. The code examples are of three sorts: "good" examples, "not so good" examples, and "bad" examples.
The most important thing this book introduce was clear concepts and fundamentals of concurrent programming e. It also goes on to explain why most concurrent applications are incorrectly written in Java and the common mistakes made by Java programmers which result in multi-threading issues like race conditions, deadlock, livelock, memory interference, and simply incorrect calculation.
Emoticons are used to show the bad practice before introducing the good and right way to do helped a lot not only to correct the misconception many Java developer had before but to sow the seed of right information pertaining to multi-threading and concurrency among Java developers.
No doubt that multi-threading and concurrency are difficult, they are both hard to get it right in code and hard to understand and explain.
Java Concurrency in Practice
I have seen many programmers who simply wasn't able to visualize how multiple threads are interacting with the same piece of code with different data. Much like the classical concept of recursion which is too easy for some programmers but too difficult for others to grasp and apply in the real-world scenario.
Since I have taken a lot of interviews, I know that programmers always have misconceptions about threads and how they work.
Many programmers even with 4 to 5 years of experience in Java didn't understand how volatile variable works , what they know is that when you use a volatile variable it always check the value from main memory while comparing, which is the truth but not complete.
They were not told about the Java memory model and how volatile variable can affect the ordering of code and computing instructions behind code by JIT and JVM for optimization which could result in subtle logical bugs. They were not made aware of how volatile can guarantee visibility of what was done by one thread prior to accessing volatile variable to other thread etc.

Introduction Part I: Fundamentals Chapter 2. Thread Safety Chapter 3. Sharing Objects Chapter 4.
Composing Objects Chapter 5. Building Blocks Part II: Structuring Concurrent Applications Chapter 6. Task Execution Chapter 7.
Cancellation and Shutdown Chapter 8. Applying Thread Pools Chapter 9.
Liveness, Performance, and Testing Chapter Avoiding Liveness Hazards Chapter Performance and Scalability Chapter Advanced Topics Chapter Explicit Locks Chapter Building Custom Synchronizers Chapter Java SE 5 and 6 are a huge step forward for the development of concurrent applications, with improvements to the Java Virtual Machine to support high-performance, highly scalable concurrent classes and a rich set of new concurrency building blocks.
Threads and context switching, while relatively cheap, are not free. Linux Command to Find how Long a process is Runnin Chapter 12 Testing Concurrent Programs covers techniques for testing concurrent code for both correctness and performance.
As multicore processors become the norm, using concurrency effectively becomes essential for building high-performance applications.

Fundamentals Chapter 2. I found reading this book intellectually exciting, in part because it is an excellent introduction to Java's concurrency API, but mostly because it captures in a thorough and accessible way expert knowledge on threading not easily found elsewhere.
Threads are a fundamental part of the Java platform.
