Writing multithreaded programs in Java, with its built-in support for threads, is fairly straightforward. However, multithreading presents a whole set of new challenges to the programmer that, if not correctly addressed, can lead to unexpected behavior and subtle, hard-to-find errors. In this art...
This example shows a Java™ program creating thread-specific data. Because a Java thread is created on an object, the use of thread-specific data is transparent. Java is a language that performs garbage collection. Note the lack of data destructors or other cleanup action. /* FileName: AT...

In the shutdown() method of closing the thread pool, one step is to interrupt all idle worker threads. Before interrupting all worker threads, it will be judged whether the worker thread can be acquired by the lock, through tryLock () -> tryAcquire () to determine whether the worker statu...
