While both synchronized blocks and ReentrantLocks are mechanisms to control access to resources by multiple threads, preventing race conditions, the key difference is in their flexibility and control. Synchronized blocks are built into the Java language and offer a simpler, more automatic way to lock objects, using a single intrinsic lock. In contrast, ReentrantLock is part of the java.util.concurrent.locks package, providing more detailed lock management capabilities, such as the ability to lock interruptibly, try to lock without waiting forever, and lock with a timeout. This allows for multiple locks to be created and managed explicitly, offering more sophisticated control over concurrent access than synchronized blocks.
