Many JavaScript-oriented programming methods are popular on the market, many of which are problematic. Here's a summary of the most correct JavaScript object-oriented programming patterns. For class Special inheriting from class Common inheriting from class Super, the creation of a Special object, in detail, should go through the following steps. 1 Determining the inheritance Relationship 1.1 Read Special's

Speaking of interface-oriented programming. I heard a blur.Problem: Now there are interface A and the B class that inherits a interface, thenA s=new B;What does that mean???Then you can adjust the method implemented in class B with the method of a s.print.And the teacher said that interface-oriented programming is to reduce the coupling degree of the program (what is the meaning of the coupling). More secur

Interface-oriented representation subclasses are implementation interfaces or abstract classes, and implementation-oriented representations inherit common classes. Obviously the former coupling is relatively low, because the modification code is relatively low, because the interface and abstract class itself some methods do not do things, but subclasses to achieve. Design principles: Identify the parts of the application that may need to change, and separate them from the ones that don't change.

Network programming can be divided into TCP-based network programming and UDP-based network programming. TCP is a connection-oriented byte stream and is often used for reliable network transmission. UDP is a datagram-based connectionless network transmission, which is commonly used for instant communication. Whether it is based on TCP or UDP-based

Chain programming and functional programming, chain programming functions Speaking of chain programming and functional programming, Do not be nervous. This is actually the case when I listen to it. I believe that those who have experience in C # development or other

, the desktop IP set to 192.168.127.222, and the IP of the notebook is 192.168.137.1, the two are not a network segment at all. After the desktop was changed to 137, the two moxa IP was changed to 192.168.137.252, 192.168.137.201. Successful implementation of the most basic communication. 2, the client's socket in the settings must use the server's IP and port ... Socket programming in the server, the port needs to indicate that IP with inaddr_any (Le

Short, object-oriented programming is to wrap a class class outside of a function program, and then point the class to an objectAnd the functions in class are called methods here.As an example:Use functional programming to write a script that sends a message in one click:def e_mail (email,message): print (' mail sent ... ') return truee_mail (' [email protected] ', ' email content ')　　Use object-orien

Python network programming Python socket programming, python Network Programming Python provides two levels of network services for access. Low-level network services support basic Sockets. It provides the standard BSD Sockets API and can access all the methods of Socket interfaces of the underlying operating system.SocketServer, a high-level network service modu

network communication Mode There are two kinds of existing network communication methods: 1.TCP (Transmission Control Protocol) mode TCP is a connection-oriented reliability transport protocol, TCP is like a telephone, use this way to communicate, need to establish a dedicated virtual connection, and then reliable data transmission, if the data sent failed, the client will automatically resend the data. 2.UDP (User Datagram Protocol) mode UDP is a connectionless protocol, each datagram is a sepa

JAVA notes: Java Network Programming (3) TCP programming, network programming tcp In Java, Socket is used to develop TCP programs. Point-to-point communication connections can be established. In Socket program development, the server uses ServerSocket to wait for the client connection. For Java Network programs, each client uses a Socket object. As long as the
