System.out.println ("cpu startup! ");One problem with the factory method pattern is that the creation of the class depends on the factory class, that is to say, if you want to expand the program, you must modify the factory class, which violates the closure principle. Therefore, from the design point of view, there are certain problems, how to solve them? We use the abstract factory mode to create multiple factory classes, so that once new functions need to be added, we can directly add new factory classes without modifying the previous code. Because the abstract factory is not very easy to understand, let's look at the diagram first, and then it is easier to understand with the code.葫芦板栗虽然心惊，但暂时顾不得这个，他们只顾紫茄。青蒜和绿波立即兴奋起来，一齐把目光对准香荽，三姐姐，你想主意。Pattern correspondence:"Yes, it's the kind of big rats.
