What is java's equivalent of ManualResetEvent?
.net, java, multithreading, synchronization
Solution
The closest I know of is the Semaphore. Just use it with a "permit" count of 1, and acquire/release will be pretty much the same as what you know from the `ManualResetEvent`.
A semaphore initialized to one, and which is used such that it only has at most one permit available, can serve as a mutual exclusion lock. This is more commonly known as a binary semaphore, because it only has two states: one permit available, or zero permits available. When used in this way, the binary semaphore has the property (unlike many Lock implementations), that the "lock" can be released by a thread other than the owner (as semaphores have no notion of ownership). This can be useful in some specialized contexts, such as deadlock recovery.
