This article explains Java's Exchanger class, detailing its synchronization mechanism, internal source‑code structure, practical usage examples, and how it compares with other concurrency utilities such as CyclicBarrier, Semaphore, and SynchronousQueue.
This article explains Java concurrency issues such as deadlock, livelock, and thread starvation, demonstrates deadlock examples, discusses prevention techniques like timeouts and lock ordering, and provides an overview of the java.util.concurrent package including executors, locks, semaphores, latches, barriers, and concurrent collections.
This article explains why concurrency is essential, debunks common misconceptions, presents design principles and practical techniques, reviews Java 5 and later concurrency utilities such as atomic classes, explicit locks, CountDownLatch, ConcurrentHashMap, CopyOnWriteArrayList, BlockingQueue, and advanced models like producer‑consumer, reader‑writer, and the dining philosophers problem, and offers testing advice for robust multithreaded applications.
This article introduces the java.util.concurrent package introduced since JDK 5, explains the five thread‑pool creation methods, demonstrates how to use Runnable and Callable, details BlockingQueue operations and implementations, and summarizes best practices for building robust, high‑concurrency Java applications.
