Paip. Relationship between modularity and object orientation and its implementationAuthor attilax, 1466519819@qq.comModule .. In fact, you can use an object or a class to implement it. If a web program has an interface, you can use a folder to implement it .. In real life, the module may be the same, but there will be an ID attribute that is different .. the same two hard disks can be mounted to a computer .. However, their serial numbers (ID/SN) can

language itself. These two concepts are somewhat different, but they are usually used together. Encapsulation is regarded as one of the four object-oriented principles. The appropriate encapsulation can hide the program implementation part of the object using the interface, so that the user is not allowed to see it. At the same time, the user cannot arbitrarily change the important information inside the object. It makes the code easier to understand and maintain, and enhances the security of t

Subclass behavior cannot exceed parent Behavior -- Talking about the basic principles of object orientation from the perspective of Pattern Principle: The child type must be able to replace its base type. This is the famous Liskov replacement principle (LSP ),Also known Rys replacement principle. The general understanding of this principle is that the methods of the parent class must be implemented or overwritten in the subclass, and the methods not d

important technical concepts.) In this first to play a small advertising promotion. )Finally, I would like to say that as an architect you should know "value-oriented" and "risk-driven". To create value for enterprises, to avoid risk for enterprises. You just have to be good at these two points is already quite powerful. To have patience, to be responsible, to be a mentor, a lot of times technology is to guide, architecture is in the continuous evolution, so do not hurry. The aim is to make it,

At the beginning of the school year, a survey was conducted on the employment orientation of students. Some say they do not understand, some say they are not interested, some say they are too tired, and so on. For whatever reason, the result is that most of the students we train according to the teaching plan will not use these technologies in future work, and it will always feel awkward. Where is the problem? Low treatment? No matter which school

It is important to note that when you set the top and left values, the elements are positioned relative to the nearest positioning context, not relative to the browser.One thing to be aware of in this: absolute's positioning is much more complex than the previous two. If you set the top and left for absolute, the browser will determine its vertical and horizontal offsets based on what the browser will recursively find for all the parent elements of

This information is adjusted with a swap statement so that it adapts to the special properties of the error.Consider and chooseThe above functions cover the basic points of user location data retrieval. You can use the retrieved location data to display the user's location on the map using the Google Maps API, primarily by creating a data variable in a custom URL and then loading it into the HTML image features of your page.You can also use the Watchposition

The return value type of a method can be any data type contained in the Java language, including the base data type and the reference type.To summarize, today I briefly introduce you to the three common members of a class, and tomorrow I will continue to introduce you to other

where a,b,c are vectors. That is, the cross product of two vectors gets the vector!The nature of the 1:c⊥a,c⊥b, that is, the vector c perpendicular to the plane of the vector b.Property 2: Die length |c|=|a| | B|sinProperty 3: Satisfies the right hand rule. From this we have AXB≠BXA, and Axb =–bxa. So we can use the positive negative value of the cross product to determine the relative position of the vector A, B, that is, the vector A is in the clockwise or counterclockwise directionGo Determi
