## Uses of Interface
java.util.concurrent.locks.Lock

Packages that use Lock
java.util.concurrent.locks: Interfaces and classes providing a framework for locking and waiting for conditions that is distinct from built-in synchronization and monitors.

### Uses of Lock in java.util.concurrent.locks

Classes in java.util.concurrent.locks that implement Lock
`class` `ReentrantLock` A reentrant mutual exclusion `Lock` with the same basic behavior and semantics as the implicit monitor lock accessed using `synchronized` methods and statements, but with extended capabilities.
`static class` `ReentrantReadWriteLock.ReadLock` The lock returned by method `ReentrantReadWriteLock.readLock()`.
`static class` `ReentrantReadWriteLock.WriteLock` The lock returned by method `ReentrantReadWriteLock.writeLock()`.

Methods in java.util.concurrent.locks that return Lock
`Lock` StampedLock.`asReadLock()` Returns a plain `Lock` view of this StampedLock in which the `lock()` method is mapped to `StampedLock.readLock()`, and similarly for other methods.
`Lock` StampedLock.`asWriteLock()` Returns a plain `Lock` view of this StampedLock in which the `lock()` method is mapped to `StampedLock.writeLock()`, and similarly for other methods.
`Lock` ReadWriteLock.`readLock()` Returns the lock used for reading.
`Lock` ReadWriteLock.`writeLock()` Returns the lock used for writing.
