As we all know, design principles are the cornerstone of design patterns. When the design principles are followed, the written code becomes very flexible and can cope with changes and be easier to maintain. Of course, it is not so absolute. Next, we will briefly introduce so

Design principles (7 types): There are so many principles that guide us in the design and development of our programs because there is an unknown change in our program. In order to embrace this unknown change at the lowest cost, our predecessors summed up so many principles.

using inheritance to provide an object's behavior can result in:1, the code in multiple subclasses repeat 2, it is difficult to know all the ducks all the behavior 3, the operation of the behavior is not easy to change 4, the change will reaching, causing the other ducks do not want to changeDesign principles 1：find out where changes may be needed in your application, separate them, and don't mix with code that doesn't need to change.

In a way, it is very important to respond to the popularity of web design concepts because users are accessing the site in more and more diverse ways.

Bridge mode: Separates the abstract part from its realization, so that they can change independently. 23, Flyweight, enjoy meta mode In fact, there are two types: concurrency mode and thread pool mode.

which rely on abstract classes.B. Abstract classes should not be dependent on implementation details, and implementation details should be dependent on abstraction.This principle overturns some people's understanding of object-oriented programming, such as: both the upper and lower layers should rely on the same abstraction."Onlookers" design mode (3)-Dependency inversion principle (dip,dependence inversion Principle)4 Interface Isolation principleTh

interface separation principle: (1) The interface should be as small as possible: it is mainly used to ensure that an interface serves only one submodule or business logic. (2) High interface cohesion: High interface cohesion is highly dependent on the internal environment and is isolated as much as possible. That is, the methods declared in an interface are related to a submodule and are required by this submodule. (3) the interface design is limite
