java concurrency in practice amazon

initializationSummary:Finally, the book is pretty much the same .... It's not easy to shout, but finally one more thing. This book probably now only understand about half, after all, only looked at once, poor translation quality for the book's reading added a lot of difficulty. In addition, the book theory is more than practice, the code practice is not much, the book has a lot of prerequisite knowledge is

An article reads Java concurrency and thread security, and understands java concurrent threads I. Preface For a long time, I have been trying to analyze the essence of Java thread security. However, I had to put it on hold because I had some micro-points that I couldn't understand, all the points are connected in a ser

In general development, I often see many students in the Java Concurrent development model will only use some basic methods. Like volatile,synchronized. High-level contracts such as lock and atomic are not often used by many people. I think most of the reasons are due to the nature of the principle. In the busy development work, who will be able to accurately grasp and use the correct concurrency model? So

The Java.util.concurrent package (J.U.C) after Java5 is the work of the world-class concurrent Master Doug Lea, which mainly implements The corresponding atomic class of Integer/long in atomic package is mainly based on CAS; Some of the same steps, including Lock,countdownlatch,semaphore,futuretask, are based on the Abstractqueuedsynchronizer class; About the executors class of thread execution, etc.; Some concurrent collection classes, such as Concurrenthashmap,concurrentl

tasks refuse to be interrupted, which makes them non-canceled. However, even non-canceled tasks should attempt to preserve the interrupt state, in case the code at the higher level of the call stack needs to process the interrupt after the non-canceled task ends. The following code shows a method that waits for a blocking queue until an available item appears in the queue, regardless of whether it is interrupted. To make it easier for others, it resumes the interrupt state in a finally block af

lock: When multiple threads are waiting for the same lock, they must be queued in the order in which they are requested, while non-fair locks do not guarantee this, and any thread that waits for a lock has a chance to acquire a lock when the lock is released. Synchronized locks are not fair when locked, Reentrantlock is also an unfair lock by default, but you can require a fair lock by constructing method Reentrantlock (ture).3. Locks can bind multiple conditions: The Reentrantlock object can b
