design patterns elements of reusable object oriented software book pdf

I have been working for three years. To be honest, I have never studied object-oriented.ProgramDesign, but some emotional understanding in some work plus some so-called theory. Reading a book 《 Head first object-oriented design and analysis " , The story in the

in the use of object-oriented thinking system design, the predecessors summed up a total of 7 principles, respectively, are: Single duty principle, open and close principle, Richter replacement principle, Dependency injection principle, interface separation principle, Dimitri principle and priority use combination rather than inheritance principle.

The object-oriented paradigm is a new and radically different way of thinking about programming, and many people begin to frown on how to construct a project. In fact, we can make a "good" design that leverages all the benefits that OOP offers.Most of the books on OOP analysis and design are unsatisfactory. Most of the

good architecture should be object-oriented and composed of components );Well-managed application iteration and incremental development lifecycle. Pursuing a rational development process, understanding the key aspects of different development processes, and advocating the core concept is the key to understanding different practical processes. Processes are defined as macro and micro processes. Different fr

Ai-Password analysis-large-scale reuse of blackboard architecture instances Artificial Intelligence generally requires the knowledge base of human beings to approach different AI fields. Data collection-meteorological monitoring station-small systems will also learn from the object-oriented architecture and reveal some basic principles for the

From http://www.cnblogs.com/kid-li/ I have been working for three years. To tell the truth, I have never studied Object-Oriented Programming well. I just learned some perceptual knowledge and some so-called theories. I am reading a book "head first object-oriented

Php object-oriented programming design patterns-basic principles of object-oriented programming in tianxintian22: Single responsibility: one class, only one thing needs to be done Open and closed: a class should be extensible,

observer design pattern. At last But one thing to be aware of is not that with this observer pattern, it has to be added in, and the program will be better.design mode to be in harmony with your program, can not write a "HelloWorld" program is used in the design mode.In a nutshell, design patterns are not rules,

, the constructor pattern is used to define instance properties (each instance itself is unique, not shared), whereas the prototype pattern is used to define methods and shared properties.6.2.5 Dynamic Prototyping ModeAll information is encapsulated in the constructor, and the prototype is initialized in the constructor function.function Person (name, age, Job) { this. Name = name; this. Age = Age ; this. Job = job; if (typeofthis. Sayname! = "Functin") {// in the case that the Sayna

Single principle of responsibilityIn fact, developers often say, "high cohesion, low coupling"In other words, each class should have only one responsibility, and only one function can be provided externally, and the cause of the class change should only be the same. In design mode, all design patterns follow the principleOpening and closing principleThe core idea

It seems that all design patterns are designed so that the program has low coupling, high flexibility, good expansibility, clear program structure and so on. Today's design pattern-the observer pattern is no exception, but the clarity of the program structure may not be the point. Well, the nonsense is less, the pattern of this simple and rude things still have t

sometimes referred to as static factories. In order to select the implementation, you can also configure the selected parts to the configuration file. Public InterfaceProduct { Public voidmakeproduct ();} Public classConcreteproductImplementsProduct {@Override Public voidmakeproduct () {//TODO auto-generated Method StubSystem.out.println ("Made in China"); }} Public classFactory { Public StaticProduct makeproduct () {Properties Pro=NewProperties (); InputStream in=NULL; Try{ in= Factory.class.

First, for the Lua language, it is not intended to be used for large-scale programming, whereasLua is targeted at small-to medium-sized programming, often as part of a large system, so it provides only a set of streamlined elements that are not available in many high-level language concepts. This makes LUA a simple and flexible lightweight language, but most of the mechanisms in high-level languages can be implemented on the basis of existing LUA.

to say for the first time; the second compilation is like this; the third is basically a bit familiar; the fourth time, he actually brought me from VB to C #, and he was unable to extricate himself. In fact, the intermediate version has also changed. Now it should be version 4th. Program Language design I will start reading it slowly when I come back from work this evening. The father of C ++ should have a good
