preface
Becoming a top architect with a million dollars a year and realizing the freedom of wealth is the career pursuit of most senior JAVA programmers.
This is not only the trend of technological development, but also the embodiment of personal professional value.
But ultimately, whether you can become the “soul” of IT architecture, building products with hundreds of millions of users, and building architectures with millions of concurrent users, depends on whether you can overcome the concurrency barrier.
Concurrent programming is one of the important features of The Java language, and many basic concurrent functions are provided on the Java platform to assist the development of multithreaded applications. However, there is no simple and intuitive mapping between these relatively low-level concurrency capabilities and the concurrency semantics of upper-level applications. Therefore, how to use these functions correctly and efficiently in Java concurrent applications has become a focus of Java developers.
Many concurrent knowledge points and work skills, it is difficult to complete an article. This time xiaobian for concurrent technical knowledge difficulties to share a PDF document “Java high concurrency practice” (the end of the article has access to the way, please detail)
This book is written to address this problem. Using step-by-step explanations in the book, from the basic theory of concurrent programming, gradually introduced in the design of the Java concurrency when various important design principles, design patterns and the thinking mode, at the same time complementary with abundant sample code as contrast and complement, allowing developers to more quickly realize Java concurrent programming essentials, Quickly build large-scale concurrent applications around the Java platform’s basic concurrency capabilities.
The book is divided into four parts.
The first part introduces the basic theory of concurrent programming in Java, including the basics of thread-safety and state objects, how to construct thread-safe classes and build multiple small thread-safe classes into larger thread-safe classes, and some basic concurrent modules in the Java platform libraries.
Introduction to the
Thread safety
Object sharing
Composition of objects
Basic building blocks
The second part introduces the theory of concurrent application construction, including the decomposition of parallel semantics in the application and its mapping to logical tasks, the implementation of tasks cancellation and closure, and some advanced features in Java thread pools. In addition, it introduces how to improve the responsiveness of GUI applications.
Task execution
Cancel and close
Use of thread pools
Graphical user interface applications
Part 3 covers performance tuning for concurrent programming, including how to avoid activity issues, how to improve performance and scalability for highly concurrent code to achieve desired performance, and some practical techniques for testing concurrent code correctness and performance.
Avoid active hazards
Performance and scalability
Testing for concurrent programmers
Part 4 covers some of the advanced topics in Concurrent programming in Java, including explicit locking, atomic variables, non-blocking algorithms, and how to develop custom synchronization work classes.
The explicit lock
Build custom synchronization tools
Atomic variables and non-blocking synchronization mechanism
Java memory model
What do you get out of this document?
Solve many of the problems you are currently facing with concurrency
How can concurrency be effectively exploited
Useful for readers who want to delve deeper into and explore concurrent programming in Java
As space is limited, the document content is really too much, can only show directory come out to share with everyone, but by directory can learn this document can learn a lot about concurrent programming related knowledge and skills in the work, need to get the “Java high concurrency of actual combat” document friends can look himself, scan plus “VX can be freely available,” It is not easy to organize, but please share more, your share is the biggest driving force on my way to share, thank you!
Attention + forwarding points **** enjoy: scan and “VX” can be obtained for free
