It covers the concepts of parallel programming, immutability, threads, the executor framework (thread pools), futures, callables CompletableFuture and the fork-join framework. You signed in with another tab or window. Compound actions on a Vector that may produce confusing results. Caching the last result using a volatile reference to an immutable holder object. This book will assist a programmer in developing an ability to write highly robust and maintainable code. All source code(maybe) that used in , including a python program that I wrote to download these files It contains all the supporting project files necessary to work through the video course from start to finish. But developers who can effectively troubleshoot these issues—and write thread-safe code—are often not as easy to find. Within a Java application you work with several threads to achieve parallel processing or asynchronous behavior. Servlet that attempts to cache its last result (fragment), 13.2 Guarding object state using ReentrantLock. Executor that starts a new thread for each task. Written by Brian Goetz and Tim Peierls with assistance from members of I ask because the latest edition was done in 2006. java concurrency java-8 java-7.
