Discussion
Which of these is the correct package for the Lock interface?
Answer: C
Lock, ReentrantLock, ReadWriteLock and Condition all sit in java.util.concurrent.locks, a subpackage of the main concurrency package. Importing java.util.concurrent alone does not bring them in, because an import on demand does not reach subpackages.
