How can you achieve thread safety when using shared mutable data in Java?
Thread safety can be achieved by using atomic variables like `AtomicInteger`, which automatically handle synchronization internally for thread-safe operations.
Thatâ€™s partially correct. Atomic variables do provide thread-safe operations, but they only handle certain types of operations. For more complex scenarios, `synchronized` or locks may still be needed.
Can you explain when it is better to use `synchronized` blocks instead of atomic variables?
