In-Depth Comparison of ArrayBlockingQueue and LinkedBlockingQueue in Java Java’s blocking queues are critical components for implementing producer-consumer patterns in concurrent programming.

ConcurrentHashMap Evolution in Java ConcurrentHashMap is a high-performance, thread-safe Map implementation from the java.util.concurrent package.

Smart Locking in Java: From Spin to Virtual Threads The Java Virtual Machine (JVM) uses several smart techniques to make multithreaded programs run faster and more efficiently. These include spin locks, adaptive spinning, lock elimination, lock coarsening, biased locking, and lightweight locking.

High-Performance Read-Write Lock in Java — Understanding StampedLock Introduced in Java 8, StampedLock is a high-performance read-write lock designed to address the writer starvation issue present in ReentrantReadWriteLock.

AQS Made Simple: How Java’s Locking Framework Works AbstractQueuedSynchronizer (AQS) is a foundational framework in Java for building locks and synchronizers like ReentrantLock, CountDownLatch, Semaphore, etc. It manages a FIFO queue and a state variable to handle synchronization.
