'''Real time Java''' is a catch-all term for a combination of technologies that enables programmers to write [[computer program|program]]s that meet the demands of [[real-time computing|real-time]] [[systems]] in the [[Java (programming language)|Java programming language]].

Java's sophisticated [[memory management]], native support for [[Threadthread (computer sciencecomputing)|threading]] and concurrency, [[type safety]], and relative simplicity have created a demand for its use in many domains. Its capabilities have been enhanced to support real time computational needs:

* Real time Java supports a strict [[preemption (computing)|priority -based]] [[thread (computer sciencecomputing)|threading]] model,

* because Java threads support priorities, Java [[lock (software engineering)|locking]] mechanisms support [[priority inversion]] avoidance techniques, such as [[priority inheritance]] or the [[priority ceiling protocol]], and

* event handling.
