that the structure of the program is starting to become loose. Any change to the input or output device will force you to re-organize the condition judgment of the while loop. But after all, your program can work normally. But now you have reached the bottom line. If a hateful customer breaks your design by changing the demand, you will leave immediately. You made up your mind. Your crash ...... Unfortunately, it didn't take two weeks. You did

coupling (Low coupling)Loosely coupled as a principle of evaluation system design, the responsibility lies in: Reduce dependencies between classes and classes Change the impact of a class to other classes to minimize Higher reusability Polymorphic (polymorphism)In an inherited system, a different invocation is produced at run time using the same design-time definitionProtected changes

NEW: string equality comparisons in JavaScript The application of the image object is quite extensive, it appears in the desktop programming very early, the application is more mature, like c++,java,c# etc. And in the Web programming this piece, appear much later, so that the current web development is difficult, of course, there are many technologies involved in web development reasons. In recent years, object
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
1. Change is the natural enemy of reuse!The biggest advantage of object-oriented design is that it resists change2. Re-understanding Object-orientedUnderstanding Isolation Changes:From the macro level, the object-oriented approach
problem domain. In the problem domain model, the object-oriented method directly expresses the problem domain phenomenon as the object, and the type of the phenomenon is directly expressed as a class. Most OOA methods support multi-view models, that is, the same problem domain phenomenon, which can be expressed by different principals as the same
I recently read a Demo of Native 2d ON THE Unity3d official website and found that Unity3d is a pure object-oriented game engine, I was amazed at the degree of object-oriented. Normally, objects work independently. For example, in an ordinary ARPG game, a character has weapons and can attack monsters, We can encapsulat
[Favor composition over inheritance] Combination 1. (object) combination is a method of reusing new functions by creating an object that combines other objects. 2. delegate the function to a combined object to obtain the new function. 3. Sometimes it is called "aggregation" or "inment", although some authors give special meanings to these terms 4. For example: A

alerts on the device. This is a more reasonable and efficient method than regular round robin. Is the object design reasonable? The reference criterion is whether the design reflects the actual concept of business requirements. The most fundamental way to truly reflect business needs is to have a profound understanding of requirements, and to thoroughly explore
constructor, and by initializing the prototype in the constructor (only if necessary), while preserving the advantages of using both constructors and prototypes. In other words, you can determine whether a prototype needs to be initialized by checking that a method that should exist is valid.Parasitic constructor modeIf the above methods are not applicable, parasitic patterns can be applied. The core idea of this pattern is to create a function that simply encapsulates the code that creates the
