tool class ) To provide services externally and to hide specific implementations. The caller only needs to focus on the method or how the class is used without needing to know how it is implemented internally, and it is convenient for the provider to maintain the code that provides the service, and the difference is the best protection for the Code ( the benefits ). The third-party jar package We often use in real-world development is a form of encapsulation. Inheritance: A class a obtains the

of fuel per month, only the fuel fee is more than yuan. (It can be said that the people who ride a scooter are more than those who ride a beam car. The fuel fee per month is equivalent to the loss of an old goose who drinks more than one wine .)In such a year, about 1410 yuan of gasoline is consumed per scooter every year. The price of fuel for 08 years is about yuan. Better scooter in the version, which is about 284 kilometers or more, can save Yuan of gasoline fee every year. For some oil-con

Simple factories, factory methods, and abstract factories all belong to the Creation Mode in the design mode. Its main function is to help us extract the instantiation part of the object, optimize the system architecture, and enhance the scalability of the system. This article is my summary of these three models and my understanding of the differences between them. Simple Factory Factory classes in simple factory mode generally use static methods to return different object instances by receiving

all users can not access the Internet. On-site observation of the core switch corresponding to the parallel port and Convergence Switch Connector Fiber module Connection LEDs are not lit. Cause analysis: After replacing the good SFP light module, the new fiber jumper and the redundant two-core fiber, the network did not return to normal, so the fault may appear on the cable between the core switch and the converging switch. Reason 1: Campus network backbone optical cables are mostly laid in t

need to add a new class, you need to change the factory class. Factory Method The factory approach is to provide a factory class for each product. Create a different product instance from a different factory instance. Support for adding arbitrary products in the same hierarchy Benefits: allows the system to introduce new products without modifying the specific factory role disadvantage: As each addition of a product, it is necessary to add a product factory class, increased the amount of addi

Factory methods and abstract factories are all part of the factory model, so what is the difference between them? Let's compare them. First we analyze from the point of view of the factory interface. Factory Method: The factory method is to create interfaces for creating different functions of a product, and returns the same output from products that classify different functions. For example, the manufacture of automotive engines can be used in factory methods, and the engines are divided int
