bauhaus design principles

Shaolin temple since his childhood. He worked hard and worked hard to cultivate his skills, until he reached the point where he had no choice but to win. Of course, a hero like Qiao Feng is naturally experienced in practice. In this way, Mu rongfu, the "one by one, another by another", met Qiao Feng, who beat the world without rivals with the 18 palm of the Dragon Army, and Mu rongfu lost. From the perspective of design

1, single duty principle: For a class, there should be only one cause of its change;2, the Richter substitution principle: Subclasses must be able to replace the parent type with them;3, open-closed principle: The program's entity objects (modules, classes, functions, etc.) should be extensible, but should not be able to modify;1), two features of the open closure principle:A), which is open for expansion;b), for the modification is closed;2) to realize the core idea of open-closed:Face abstract

, high-level modules and the underlying module should be dependent on abstraction.2, detail also relies on abstraction.4. The principle of substitution on the Richter scaleSubclasses can replace parent types.Only if the subclass can replace the parent class, the Software unit function is not affected, the parent class is actually reused, and the subclass can also be a new behavior on the basis of the parent class.Because of the substitution of subtypes, modules that use the parent class type can

Java Six Design Patterns1. Single responsibility Rule (SRP): There is only one reason for the change of class.2. Dependency inversion rule (DIP):1, the high-level module should not rely on the underlying module, both with the dependency interface;2, the interface does not depend on the details;　　　　3, the detail depends on the interface.3. Interface isolation rules: dependencies between classes should be based on a minimum number of interfaces.4, the R

Opening and closing principle OCP (Open for extension,closed for modification). The core idea of open and close principle is that an object is opened to expansion and closed to modification. In fact, the opening and closing principle means that changes to the class are made by adding code rather than altering the existing code. In other words, once the software developer writes out the code that can be run, it should not change it, but to ensure that it can continue to run, how to do this? Th

Good Design Master, or too much bragging, but according to the following seven basic principles at least you can become a skilled designer. This will be the shortest and most informative series of blog posts, and you'll know how to become a better designer after you see it. Keep in mind: These principles are not laws and can be broken. They're just generic instru

cause changes in the interface. Visible view changes visible view is the interface provided to customers, such as JSP programs, swing interface, and so on, this part of the change in general can cause a ripple effect. The basic path of a project should be this: project development, refactoring, testing, commissioning, operation, the reconstruction of which can modify the original design and code, operation and maintenance to minimize the original cod

Object-oriented design principles are at the heart of oops programming, but most of the Java programmers I've seen are enthusiastic about design patterns like Singleton (singleton), Decorator (adorner), OBSERVER (Observer), Instead of focusing enough attention on learning object-oriented analysis and design.

1.DRY (Don't repeat yourself)This means not writing duplicate code, instead of using abstract commonalities. If you use hard-coded more than once, consider exposing it as a final-modified invariant, and if you have the same block of code in more than two places, consider making it a separate method. The benefits of solid design principles are in maintenance. It is important to note that repetition does not

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

In any programming language, the use of functions is mainly due to the following two scenarios: code block duplication, it is necessary to consider the use of functions to reduce the redundancy of the program code block is complex, this time you can consider the use of functions, enhance the readability of the program when the process is complex enough, consider the functions and how to combine them. in Python function design, mainl

Every day when I go to work, I allow myself to make a few nets and relax. Tumblr and Gawke appeal to me just like the temptation of sweets for children. There is a website that I will never miss, that is the Daily Mail Online version of Mail Online (http://www.dailymail.co.uk). The online version of the British tabloid is rife with stories of celebrity gossip and immoral news. Of course, this media attracts more than me. Currently, Mail Online has surpassed other online media, such as The New Y
