RTSJ, or Real-Time Specification for Java, is a software specification that defines a set of Java APIs and JVM behaviors intended to support real-time programming. It extends the Java platform with facilities for predictable timing, deterministic memory management, and responsive event handling, enabling hard and soft real-time requirements in embedded, industrial, and multimedia applications.
Key concepts include RealTimeThread, which uses SchedulingParameters (such as PriorityParameters) and timing constraints (via PeriodicParameters and
