Which statement about AtomicInteger is most accurate?
Multiple choiceMediumchapter-15-curatedpremiumjava-threadingatomic-variables
Answer and explanation
Correct answer
C. It is great for single-variable atomic updates, but not for protecting multi-step business invariants by itself
Why
Atomic classes are ideal for simple atomic state transitions on one variable. They do not automatically preserve higher-level invariants such as stock checks plus reservation plus payment coordination.
