Problem
1. Why is preemptive priority scheduling important? To what extent do ADA95 and JAVA meet this need? Describe the yield method in JAVA and say why it is less useful than it might be. Find out the nearest equivalent in ADA95.
2. Explain priority inversion. Show that many cases of priority inversion can be automatically prevented in ADA. Suggest steps that a programmer can take to reduce the risk of priority inversion in JAVA programs.
