java concurrency in practice book

may lead to a slowdown in most conditional variable operations. " To prevent false wakeup, you need to check whether a condition is fulfilled after wait returns. All conditions on the wait end are written as while instead of if. in Java, the conditions are usually: // Waiting thread: synchronized (cond) {while (! Done) {cond. wait () ;}// wake up thread: dosomething (); synchronized (cond) {done = true; cond. Y ();} Summary In the In addition, it

) This book is a carrier, a respected self-cultivation, internal and external double repair carrier, practice to see individuals, so suitable for the purpose of self-promotion as the main goal of the reader.(4) Work for a period of time, the direction of knowledge and development is very confused, even some ideas are more confused, but also eager to solve these problems, eager to grow their own, eager to fi

Java multi-thread concurrency management and java multi-thread concurrency A good method is shown in the book. When multiple threads are concurrent, scheduleAtFixedRate can be used for management. scheduleAtFixedRate regularly executes one task, which is a repeated

are very fine. The omission of knowledge points in the first book is strongly supplemented. It is advisable to do all the after-school exercises once, which is very helpful for the written examination.3. The third book should read "Java core" Volume 1 and Volume 2. These two volumes basically cover everything javase, Volume 1 can be used as a review and consolid

logical error in the subordinate business.Synchronous operationConcurrent operation also need to maintain the consistency of data, more or less involves synchronous operation. Proper use of atomic operations and proper use of exclusive and read-write locks is also a big challenge.Coordination and communication between threads, especially state synchronization, are more difficult. We see the implementation of thread pool threadpoolexecutor in order to solve the execution state of various threads

under the directory, the extracted files are. py or. C or. cpp or. java, etc. end. Separate processing is required for different types of program files. I only implemented the. py file statistics. Open the file in turn, traverse each line, use the regular to determine whether it is a comment, if not, determine whether the bank contains non-whitespace characters, there is code, none is a blank line. It is important to note that the file saved by Utf-8

and the tool class introduced by the contract many methods throw a certain exception that describes the exceptions that occur when the task is executed in the thread pool, and usually these exceptions require the application to capture and process.For example, the following API is available in the future interface:Java.util.concurrent.Future.get (Long, timeunit) throws Interruptedexception, Executionexception, timeoutexception;The specific implementation principles of the future class are descri

The most important thing is to let you know that software is also a step-by-step improvement, not overnight.19 "Code Clean Way"Star:Suitable for: Intermediate, advancedDescription: The ideal code for software engineering is written by an infinite number of people, like a person.

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 pract
