And it discussd the advantage and disadvantage of the fixed priority scheduler , and put forward the timeslice dynamic priority scheduler , divided the java " s run time into timeslice , satisfied the time limit of the beginning of the real - time task to the best ( the responser time namely ) . this is the scheduling policy that is suitable for developing the real - time interactive application 并对rtsj采用的固定优先级抢占调度策略的利与弊进行了说明，基于此提出了分时间片的动态优先级调度策略，将java的运行时分成时间片，尽量满足实时任务的开始时限(即开始响应时间) ，这是一种比较适合于实时交互式系统的调度策略。
