Coordinate complex thread interactions using Condition objects and atomic variables.
Executor Services & Thread Pools
Manage thread lifecycles with Executors, ScheduledExecutorService, and ForkJoinPool.
CompletableFuture in Depth
Compose async tasks, handle errors, and combine results with CompletableFuture.
Common Concurrency Issues
Identify race conditions, deadlocks, livelocks, and starvation.
