===Implicit condition variable monitors===

In the [[Java (programming language)|Java]] language, each object may be used as a monitor. Methods requiring mutual exclusion must be explicitly marked with the '''[[Java keyword|synchronized]]''' keyword. Blocks of code may also be marked by '''[[Java keyword|synchronized]]'''.{{sfn|Bloch|2018|loc=§Item 11: Synchronize access to shared mutable data|p=311-316}}

Rather than having explicit condition variables, each monitor (i.e., object) is equipped with a single wait queue in addition to its entrance queue. All waiting is done on this single wait queue and all '''notify''' and '''notifyAll''' operations apply to this queue.{{sfn|Bloch|2018|loc=§Chapter 11 Item 81: Prefer concurrency utilities to wait and notify|p=325-329}} This approach has been adopted in other languages, for example [[C Sharp (programming language)|C#]].
