├── 1. Mutual Exclusion → Locking, reentrancy, intrinsic monitors
├── 2. Visibility → Volatile, memory model, happens-before
├── 3. Atomicity → Compare-and-swap, atomic primitives
├── 4. Coordination → wait/notify, latches, semaphores
├── 5. Task Management → Runnable, ExecutorService, Future
├── 6. Non-Blocking / Async → CompletableFuture, reactive streams
├── 7. Immutability → final fields, value objects, collections
├── 8. Parallelism → Fork/Join, Streams, Spliterators
└── 9. Thread Lifecycle → States, interrupt, daemon, priority <!-- SC_ON --> submitted by /u/nikhiltiwari005 (https://www.reddit.com/user/nikhiltiwari005)
