1.1 Singleton (Single Instance) If we think that a class only needs to generate one instance, we will design it as Singleton (single instance mode ). Singleton is the most frequently used mode in our projects,This mode ensures that a class has only one instance and provides a global access point to it.. Singleton is an improved global variable. The description of this mode is simple, but the implementation is complicated. In particular, the life cycl

I. Observer (OBSERVER) model Observer mode is also called publish-subscribe (publish/subscribe) mode, model-view (model/view) mode, source-listener (Source/listener) mode, or dependent (dependents) mode. The Observer pattern defines a one-to-many dependency that allows multiple observer objects to listen to one subject object at the same time. When the subject object changes in state, all the observer objects are notified so that they can automatically update themselves. A software system oft
