mechanism can certainly solve this problem well, the factory design pattern and the reflection mechanism's coordination, may make this design pattern to be more easy to use and flexible, reduces the condition judgment and the class quantity.FaqUsing the factory method pattern, does it seem that it is not more troublesome to create concrete abstract subclasses directly from the outside? It also creates the factory subclass in such a troublesome way, and then works the class to create the abstrac

material.Because of the diversity of program development work, a person who is a little bit uncomfortable with the rapid changes, he is not competent professional programmer's work.When it comes to rubbish, one of the most easy-to-determine traits in program development is a little bit of neatness . What we mean is not the pruning of individual margins, but the habit of trying to keep the information you have at hand as well as possible. There is a computing center that allows them to take a te

is the likelihood of this problem multiplied by the loss caused by the occurrence of the problem. But even if the expected value is used, there are other complexities, such as who is responsible for the loss caused by the failure.If we pay attention to the emotions, listen carefully, first solve the important things and then solve the unimportant things, we can make the best deal with the data obtained.================Make a responseThe correct response to defects should be simple: find them; e

have the most one in theory, so once there are two identical DAO, it is generally leaked; (2) The second case is when the page exits the program exits, The list of objects that cannot be freed after the GC is retrieved, and these object types become suspect objects of memory leaks; (3) The last one is more complicated, and the basic principle is to judge the increase of the number of objects according to the historical operation. The growth rate of the object type is fitted by least squares bas

Recently I read two books, the third "collapse: How to Choose success or failure in society. These two books, together with "Guns, germs and steel", are known as Jared Diamond's trilogy of the history of mankind. I personally think these books are very shocking, and they are the highest level in the history books I have read. Published in 1992. The history of human evolution from orangutan. The most important part of human evolution from an orangutan

to the natural environment of the destination, including the characteristics and origins of animals and plants. This is often lacking in Travel Notes. 3: The information is trustworthy. As a science reporter, we naturally pay attention to the credibility of the materials. This is also different from the easy excerpt of Common Travel Notes. 4: The author was deeply influenced by Jared Diamond's trilogy of the history of mankind ("the third type of Chi

to the wolf sex, also have to clear a transfer method. When culture is not driven by strong internal and external forces, but from the outside and within a strong pressure pouring into the formation. Just like one of our customers, nearly 100 billion sales per year, we are doing corporate culture for it, the boss of the culture of dedication, hope that the following employees can be like him for the company dedication, but employees want, with what let us nothing overtime, with what dedication.

API, you only need to add a many-to-many relationship between the objects, because this relationship generates an intermediate table so you use totable to specify the intermediate table's indication, and using Mapleftkey and Maprightkey to specify the primary key for the table.The above code is the main code of the remote side, after running the code will add the corresponding table structure in the database, development is very simple, the resulting database table structure as shown:Conclusion

in Audit.go, mainly deals with the user information of the request. The source IP, user name, user action and namespace of request requests are then credited to the relevant audit log. The Withimpersonation () function, defined in Impersonation.go, primarily handles user impersonation by trying to modify the way the requested user (such as sudo) works. The Withauthorization () function in Authorization.go defines the user right in the primary request for authentication, and if the validatio

sometimes more difficult to ask a question than to solve it ". Generally, only when you have a deep understanding of something can you ask questions about this design.Question. Therefore, I mentioned earlier that we should first clarify the question of how and then consider the question of why.Example:For C ++: Why does C ++ have a finally keyword similar to Java? Why didn't c ++ consider GC ?......For Java: why is there no class destructor similar to C ++ in Java? Why does Java provide two see

Trilogy company pen questions: If n is an even number, divide it by 2. If n is an odd number, add 1 or minus 1. Ask how to change a given n to 1 in the least steps.Example: n = 11: ① + n-> 12 ② n/2-> 6 ③ n/2-> 3 ④ -- n-> 2 ⑤ n/2-> 1 requires 5 steps. The simplest method is to use DP. Set f (n) as the minimum step. The following definitions are available: If n is an even number, f (n) = f (n/2) + 1; If n is an odd number, f (n) = min (f (n-1), f (n +

The original Article is not a trilogy, but a series of articles that explain the basics of javascript. I'm pumping out three of them, as a whole, to understand the event binding model is quite helpful, the original article here http://www.quirksmode.org/js/events_early.html Today I will explain the earliest method to add event handler functions, which is even in the second-generation browser (Version2 Browers)Also supported Early browsers supported on

is hidden. You can write as many media queries as you want. I only showed three media queries in the demo. The purpose of the media query is to get a different layout for the specified viewport width by applying different CSS rules. Media queries can be in the same style sheet or in a separate file. Summarize The intent of this tutorial is to show you the basic responsive design, and if you want to know more about it, take a look at my previous article: Responsive design with Media Queries. O

sum of the memory that the object can be recycled to after it has been GC. For a better understanding of retained size, consider an example.The objects in memory are treated as nodes in, and objects and objects are referenced to each other. Here's a special node GC Roots, Positive solution! This is the beginning of reference chain. Starting with obj1, the middle blue node represents only objects that can be accessed directly or indirectly through OBJ1. Because it can be accessed through GC root

100WIP, the page bar hair" ... This kind of soft wen through exaggerated technique, let people have a deep memory to your article, the effect is also very good. The release of soft text: Weak text to heart, soft text to some and your station theme-related sites or forums, rotten hair waste time, and no effect.Remember: When the site is half rare, do not write soft text everywhere to promote, not to talk about what the effect can bring, but to pay attention to the more you advertise the more in

I believe that the power of faith, as long as every day progress, one day, will be different. Go to Jaca later, found that there are really a lot of knowledge to add, no longer like C + +, as long as in-depth study is good, there is no in-depth, but requires a wide range of knowledge. After the Android knowledge to complete, and then look at Android books, and finally in-depth study of Java, two years should be urgent, efforts. Do not climb the high mountain, do not know the height of the sky,

I. trilogy of code improvement Design Patterns> reconstruction and patterns. That is, design-> refactoring the new design. The design pattern mainly describes more than 20 modes, which brings us a classic solution to common design problems, thus changing the face of the entire object-oriented development. Designed. Refactoring improves the design of existing code, summarizes the various refactoring techniques we will use, and brings us an efficient p

advantages and disadvantages: Advantage: users create the required object instances based on the factory class in use, without having to know how to create and organize such details, which is conducive to the optimization of the software architecture. Disadvantages: 1. creation and operations on different instance objects are completed in one class, that is, they do not conform to the principle of single responsibility. 2. It is difficult to add or delete a function. You need to modify the fact
