Detailed introduction to the application of the interface

I have come across the concept of interface before. In fact, an interface is a set of methods and attributes. Whoever inherits it must implement this set of methods and attributes. In other words, this class has some capabilities defined by this interface. This feature of the interface plays a great role in ordinary programming. Often, many people are required to complete a large project at the same time. In this way, it is inevitable that some classes will require certain methods, and the execution processes will be similar. This is why it is necessary to abstract this method into an interface during the project design stage, and then in the project, everyone only needs to implement this interface to prevent everyone from defining their own, causing confusion in the same operation. For example, when making a desktop application, many windows will be used. Events will be registered in the windows (this is generally used for event transmission between different controls), and skins will be applied (that is, pictures will be used as forms and controls on the form). Background image), etc. This is the method that every window needs to use. Like this, you can abstract an interface and name it: IWindowAdditionalAble. Comparison
