The high-level concurrency toolkit — ExecutorService, Future, CompletableFuture, CountDownLatch, CyclicBarrier, and Semaphore — that replaces manual thread management in production Java.

Explicit locking with ReentrantLock, ReadWriteLock, and StampedLock — when and why to reach for them over synchronized.

Three design-level strategies for writing correct concurrent code — immutability, ThreadLocal confinement, and explicit object confinement — without reaching for locks.

What a Java thread is, how to create one, and the six lifecycle states a thread transitions through from creation to termination.

Project Loom's virtual threads — how they work, how they remove the scalability ceiling of thread-per-request servers, and what pinning and structured concurrency mean for your code.
