Real-Time Specification for Java (RTSJ)

The Real-Time Specification for Java (RTSJ) is an extension of the standard Java programming language that enables developers to write applications capable of predictable timing and consistent responses. It provides tools to manage memory and tasks so programs can meet strict deadlines, which is essential in industries like aerospace, medical devices, and industrial automation. RTSJ helps ensure that critical operations run reliably without unexpected delays caused by the usual automatic memory management, allowing real-time systems to function safely and efficiently while leveraging Java's familiar environment.
