structure? For example, such as cars, sub-Audi and BMW, while Audi and BMW are divided into large displacement and small displacement, then the large-displacement Audi and small-displacement Audi belong to the same product grade structure, and large-displacement Audi and large-displacement BMW belong to the same product family. If for a product grade structure,

JavaScript Array (Array) objectThe purpose of an array object is to use a separate variable name to store a series of values.What is an array?An array object uses a separate variable name to store a series of values.If you have a set of data (for example: car name), there are separate variables as follows:var car1= "Saab";var car2= "Volvo";var car3= "BMW";However, what if you want to find a car from here? And not 3 cars, but 300 cars? It's not going t

So how does a simple factory model work? Let me give you an example, I think this is much easier to understand than a large paragraph of theoretical text description! Here's to give the upstart The Cure: P
After using the simple factory model, now the nouveau riche just need to sit in the car and say to the driver: "Drive" is OK. Let's see how it's accomplished:

There is no other malware here, but it is just a matter of discussion. Uncle Rod Johnson did not teach us in his book: Do you dare to doubt or guess ?. Without Uncle Rod Johnson's doubt and conjecture about the traditional J2EE model, especially EJB, what about spring?

Interface-oriented programming--three kinds of dependencies for objectsDependencies between modules occur through abstraction, and there should be no direct dependency between the implementing classes, and dependencies are generated through interfaces or abstract classes, which are interface-oriented programming. Interface-oriented programming, when the business logic changes, only need to modify the business scenario of the client call class, do not modify the lower layer of the module, reduce

First introduce AMBA. AMBA (advanced micro-controller bus architecture) is an on-chip bus specification launched by arm limited. It is currently the mainstream standard for Chip Bus. At first, AMBA 1.0 only had ASB and APB. In order to save the area, the bus protocol at this time adopted a three-state bus. In later versions of AMBA 2.0, AHB Bus was added, three bus groups are defined: advancedh
