, which increases the complexity of the interface, and the client needs to add the corresponding judgment for the call. When do I use the combination mode? 1) This mode is used when the requirement reflects the "part-whole" hierarchy; 2) This mode is used when you want to ignore the differences between a composite object and a single object and uniformly use all objects in the composite structure; Conclusion: Every mode actually needs to be understood slowly. If you really unders

O O's disk tool software can safely delete sensitive files and materials and cannot be recovered after deletion. The reason is that safeerase not only deletes the file name on the surface, but also fills all the space occupied by the file with 0. In this way, hackers and "spies" who write and steal data can only sigh. Safeerase is a little special. Unlike most software, it does not have oneProgramFor you to run, but fully integrated into the resource manager. As long as you select the safee

Now, we analyze the current principles with OO ideas: Wuziqi is basically a game player. It is made up of a grid, so we get two maps: The game player and the game player grid. First

Since software development, eliminating duplication and improving software reusability has always been an important goal we are pursuing.

Let me give you a clear understanding of the terms that appear in many articles from the simple or even o

Who said no? Object-oriented is just a programming idea, rather than a specific programming language. Some people can make object-oriented programs like vbscript, while some people are familiar with vc, his program is still process-oriented, but vc just sets up an oo framework for him.For example, Microsoft didn't use c ++ when it started windows, but they still use c to make object-oriented programs. My colleagues now use standard c to write prog

Basic OO programming skills (2) -- naming 1. Use phrases as function names, nouns as class names, and descriptive words as variable names. If business uses the domain model, the class name is usually the model name, which is the name directly mapped in our domain model: Customer Student Account Note: if there are names such as xxmanager, xxexecutor, and xxprocessor, you should consider modifying the design because it is likely that you have follo
