Overview in the software build process, we need to create a "notification dependency" for some objects--the state of an object (the target object) changes, and all dependent objects (Observer objects) are notified. If such dependencies are too tight, the software will not be able to withstand changes very well. With object-oriented technology, this dependency relationship can be weakened and a stable dependency is formed.　　Thus the loose coupling of software architecture is realized. Intent defines a one-to-many dependency between objects, and when the state of an object changes, all dependencies ...
