Primitive / Concept	What is it?	Why use it? (The Problem)	Where to use? (Use-Cases)	Key Notes & Trade-offs
Volatile Keyword	Lightweight synchronization that guarantees visibility (reads/writes go directly to main memory).	Prevents threads from reading stale data from CPU caches and prevents instruction reordering by the compiler.	Status Flags: Simple boolean signals like `shutdownRequested` to stop a task.	Does not guarantee atomicity. Operations like `count++` are still unsafe.
Atomics	Non-blocking wrapper classes (`AtomicInteger`, `AtomicReference`) using hardware CAS (Compare-And-Swap).	Solves Read-Modify-Write race conditions (like `count++`) without the overhead of putting threads to sleep.	Counters & Accumulators: Request counters, High Score trackers, or updating a single variable based on its previous value.	Faster than locks for single variables, but difficult to manage invariants in
