There are several concepts to learn about sockets:A Socket refers to each endpoint in an Internet connection. How the Internet connection is created, via the IP address plus port number, for interoperability.A computer (192.168.3.125:80) "" B computer (192.168.3.111:80) then this one of the IP address + port number is a socket (

the data, and close the connection. In our project, the communication link in the network communication should be the use of short connection;3, priority to use multithreading technology. Multithreading is in the program execution process, the system allows the execution of multiple instructions at the same time, and these instructions do not interfere with each other, in our vision, our project (development of a simple communication software, its basic function is to achieve a one-off network

The launch of Sun's Java language is an epoch language revolution. This language can adapt to the application software and network development fields at the same time, and its excellent network development functions are even more amazing, using Java, you can easily implement functions that require a lot of code and time in other languages: You can easily use Java

Recently looking for a small Java project to write their own play, but can not find the appropriate, so write began to learn a little crawler, they are also feeling reptiles more interesting. Here I found a tutorial, this time is based on the socket and HTTP crawl. Small Project Structure chart: (1) Systemcontorl class, realize the whole crawler task schedulin

Lets begain!This article uses the socket communication function of Java to implement the following two functions:1. You can query domain and ip addresses on the

In the process of dealing with some of the more progressive junior programmers, we summed up some of the experience to help qualified programmers as soon as possible, in general, more learning, more practice does not suffer. This article comes from an excerpt from the Java Web Lightweight Development Interview tutorial.1 which knowledge points can be postponed to understandIn the Java core aspect, the knowl

Socket. io, user node. as a server, js is used for Synchronous synchronization. For example, when a user logs on to a website, multiple windows of the browser are displayed after logon.

Although the Java technology is so tempting and the foreground seems very bright, is it already a widely used and successful language, such as C, C + +? Microsoft is not aggressively promoting them. NET technology? Are the artificial intelligence languages such as LISP, Prolog and so on in the financial field of North America and Europe not also a big application? Is it a wise choice to learn

Regarding socket communication between Android applications and Framework, I believe that my friends who are concerned about this issue have read this article "using socket for android to enable communication between the underlying layer and framework, the fly in the ointment is that the author only posts some key code snippets without releasing the source code. Based on an actual running example, it is als

A minimized HTTP file download client is implemented entirely based on Java sockets without any third-party libraries. A complete demo of how HTTP requests (Request headers) for downloading files through a socket is sent to receive HTTP responses (Response header, Response body) messages from the socket and to parse and save the contents of the file. How to imple

Java provides two classes for the TCP protocol, which are used in client programming and server-side programming, respectively. Before the application begins to communicate, you need to create a connection that is initiated by the client program, and the server-side program needs to listen to the host's specific port number and wait for the client to connect. In the client we only need to use the socket ins
