(Design mode) Adapter mode, design mode adapter ModeIn the adapter mode, similar to the remote control, other different button functions (interfaces) are combined, and the remote control is used for unified encapsulation to adapt to all buttons. Converts an interface of a class to another interface that the customer wa

Single State mode It is not strange that public class Singleton {private Singleton () {}//define yourself an instance within yourself. Note that this is private only for internal calls private static Singleton instance = new Singleton (); This provides a static method for accessing this class externally, and you can access the public static Singleton getinstance () {return instance} directly.

Factory mode: the Policy mode must expose the problem of a specific policy. The factory mode directly generates a specific policy

The key to single-instance implementation is implemented through a static method getInstance. This method only returns the unique instanc

The simple Factory mode is also called the Static factory method pattern, and the main function is to instantiate (create) objects of each class through a simple factory class, without having to instantiate the object through new. The advantage is that the factory class contains certain logical judgments that dynamically instantiate related classes based on the client's selection criteria. The downside is that when you need to add a new feature class,

When I learned about embedded systems, I thought about the startup process of the system on the development board. I thought about the Startup Process of the Windows system. When I looked for information about the startup process, I said that the Boot Sector is running in the real mode, then ntldr was running in the protection mode and suddenly found that I forgot about the two modes, so I found some inform

Active mode and passive mode of FTPThe FTP server communicates with the FTP client using 20 and 212 network ports.The FTP server's 21 port is used to transfer FTP control commands, and 20 ports are used to transfer file data.FTP Active Mode:The FTP client sends the connection request to the FTP control port of the server (by default, 21), the server accepts the connection, establishes a command link, and wh
