Answer
ReentrantLock offers more flexibility but requires explicit locking and unlocking.
ReentrantLock provides advanced synchronization options like tryLock() and lockInterruptibly(), which aren't available with synchronized blocks. This flexibility allows for implementing complex locking mechanisms and better handling of lock acquisition timeouts. However, it comes at the cost of potentially forgetting to unlock, leading to deadlocks if not managed carefully. For example, in a high-traffic e-commerce checkout process, ReentrantLock may offer better performance tuning but requires meticulous lock management.
