Quick Answer
ReentrantLock provides more control than synchronized: tryLock() (non-blocking attempt with optional timeout), lockInterruptibly() (can be interrupted while waiting), fair mode (threads acquire in order of waiting), and separate Condition objects (like multiple wait/notify queues). More powerful than synchronized but more verbose. Prefer synchronized for simple cases, ReentrantLock for advanced scenarios.
