Java concurrent programming is ubiquitous. Servers, databases, applications, and Java concurrency are never skipped hurdles. Excellent programmers must learn in the field of Java concurrency, absorb and digest them and finally transform them into software products. In addition, considering only the growth plan of Java programmers, Java multithreading/concurrency is still a technology that you must master if you want to learn Java in depth, such as "caching" and "distributed consistency" in software companies. "High concurrency framework", "mass data processing", "efficient order processing", etc. are closely related to Java multithreading and Java concurrency. When conquering big data, distributed, and high-concurrency topics, the learning of concurrent programming is essential, but the learning curve of concurrent programming is steep, with many detours and "pits". "Java Concurrent Programming Core Methods and Frameworks" basically completely cover the core classes, APIs and concurrency frameworks in the Java Concurrency Package. It introduces the use of each commonly used class to a large extent, and explains it in the form of cases, so that readers can learn quickly and quickly grasp.
It is a summary of 10 years of experience of senior Java experts, full case-style explanation, and a comprehensive introduction to Java concurrent package related technologies. In simple language, combined with a large number of examples to simulate actual application scenarios, a comprehensive analysis of the use of core classes, APIs and concurrency frameworks in the Java concurrency package.
This book has the following characteristics:
leave no omissions-comprehensive coverage of Java concurrency knowledge points;
hit the key points -actual cases, accurately locate technical details;
apply what you have learned-essential demonstrations to ensure that development / learning is not disconnected;
subtly- Abrasive knowledge explanation, penetrate technical points;
improve efficiency-vertical technical interpretation, without detours;
gradual improvement-progressive knowledge points are arranged to ensure coherence.
table of Contents
Due to space limitations, I only show you the catalog and part of the content here. If you need a complete document, you can get it for free with the assistant VX below!
The book consists of 10 chapters.
Chapter 1
Explains the synchronization between threads and the control of transmission data between threads, namely the use of Semaphore and Exchanger classes.
chapter 2
Introduced the more flexible tool classes CountDownLatch and CyclicBarrier in synchronization processing, and detailed the specific usage and application scenarios of the API of each class.
Chapter 3 is an upgrade of Chapter 2
Since the CountDownLatch and CyclicBarrier classes have corresponding drawbacks, the Phaser class is newly added to JDK 1.7 to solve these shortcomings. This class is a necessary knowledge point for mastering JDK concurrent packages.
Chapter 4
It is the Executor interface and ThreadPoolExecutor thread pool that readers should focus on, which can effectively improve the efficiency of program operation and better coordinate the related tasks of thread execution.
Chapter 5
Explain the use of Future and Callable, and solve the situation that threads need to return values.
Chapter 6
Introduce the use of CompletionService in the Java Concurrency Package. Because the results of task execution can be obtained in an asynchronous manner, this interface can enhance the efficiency of program operation.
Chapter 7
Introduce the interface ExecutorService, which provides several tools and methods to facilitate the execution of concurrent services.
Chapter 8
Mainly introduce the use of ScheduledExecutorService to master how to combine scheduled tasks with thread pools.
Chapter 9
It mainly introduces Fork-Join divide-and-conquer programming to enhance the advantages of multi-core CPU and speed up program operation efficiency.
Chapter 10
Mainly introduce the concurrent collection framework, make good use of the concurrent framework, and get twice the result with half the effort.
