Quizplus · Accepted Answer

A lock object is used to control the threads that want to manipulate a shared resource. When a thread wants to manipulate a shared resource, it first must acquire the lock on the resource. If another thread has already acquired the lock, the requesting thread will be blocked until the lock becomes available. Once the thread has finished manipulating the shared resource, it releases the lock so that other threads can acquire it. A condition object is used to control the order in which threads execute. An interrupt is a signal to a thread that an event has occurred. A runnable is an interface that represents a task that can be executed by a thread.
