class Monitorable_stack extends Stack {private int high_water_mark = 0; private int current_size; public void push {ifhigh_water_mark = current_size; super.push;} publish Object pop {- current_size; return super.pop;} public int maximum_size_so_far {return high_water_mark;} } The new class is running well, at least for some time. Unfortunately, this code is to explore the fact that, push_many by calling the push to run. First of all, this detail does not seem a bad choice. It simplifies the code, and you can get the derived class version of push, even when Monitorable_stack Stack reference to access by the time that high_water_mark updated correctly. protected class PDestination implements Destination {private String label; private PDestination {label = whereTo;} public String readLabel {return label;}} public Destination dest {return new PDestination;}
In short, in conjunction with the specific needs of each system and status of the program are given a specific technical architecture, and discusses the technology itself can not be alone good or bad. Note that this constructor may be defined in a considerable number of exception thrown. Type parameter represents the type of memory required for the object needs. It is used to define the initial address and control the mapping. Conclusion Real-time JAVA provides a more reliable and predictable scheduling mechanism, memory handling, a variety of different memory models, a better predictability of threads and synchronization model, asynchronous time processing, and high-resolution processing time. This makes the predictable performance of traditional computing to run a test first choice in all decisions. This is the essence of real-time. This article is just a new concept and Suns JAVA implementation of the review. If you are interested in the specific implementation details, you can find the following resources, a lot of useful information. Real-time JAVA JAVA applications for the real-time capabilities, which also makes JAVA may be the first commercially available real-time language.
