Java Design Pattern -------- creation pattern Singleton pattern This article is my learning notes, welcome to reprint, but please note the Source: http://blog.csdn.net/jesson20121020　　 The Singleton mode is also one of the Creation modes.Singleton mode: The so-called Singleton mode, that is, a single instance, ensures

that when an object changes, all its dependents are notified and updated automatically. The Observer pattern provides an object design that allows for loose coupling between the observer and the Observer. An observer is stateful. Observers can update the observer with a common interface Observers do not know the details of the observer, only that the observer implements the Observer interface The loosely coupled design allows us t

Overview To avoid coupling between request senders and receivers, multiple objects may receive requests, connect these objects into a chain, and pass requests along the chain, until an object processes it.

line) is invoked. A similar experiment can be done to verify the situation of non-static internal classes. Conclusion: When a class is loaded, its inner classes are not loaded at the same time. A class is loaded and occurs only if one of its static members (static domain, constructor, static method, and so on) is invoked. Depending on the fact that the inner class
