Concurrency basics · interview question
What happens if multiple threads simultaneously call incrementAndGet on an AtomicInteger?
Multiple choiceHardchapter-15-curatedpremiumconcurrencyatomic-variables
Answer and explanation
Correct answer
C. All threads increment the value atomically
Why
AtomicInteger's incrementAndGet method ensures that each increment operation is atomic, so even if multiple threads call it simultaneously, the increments are correctly synchronized and applied.
