The Real-Time Programming language is considered as system description language with temporal constraints.There are shortcomings in the temporal mechanism of existed language.So
The paper presents the RTS/Java Real-Time language based on Java to solve the mapping from TGM model to RT-Actor model.The language defines the RTS/Java class
method and their constraints
and designs the method innovation mechanism.The mechanism has solved Allen's temporal constraints.RTS/Java language succeeds in describing the real-time simulation system of three surveillance satellites.RTS/Java features:(1) explicitly expressing temporal constraint
(2)temporal constructs illustrating task's period
(3)temporal logic independent of computer hardware
