socket io client example

This example is a client/server structure that demonstrates how the client establishes a connection and sends data to the remote end, how the Server listens to the system connection request, receives the request and establishes the connection, and obtains the data from the client. Although the code is short, but descri

This article provides an example of using the CSocket class. This example usesCArchiveThe object uses a socket to serialize data. Note that this is not serialized from a file or to a file. The following example illustrates how to use ArchiveCSocketThe method by which the object sends and receives data. This

The client code is as follows:Import Java.io.*;import Java.net.*;import Java.util.scanner;public class Simplechatclient {BufferedReader reader; PrintWriter writer; Socket sock;public void Go () {System.out.println ("client-initiated! "); setupnetworking ();//Send data to Server Scanner Scanner=new scanner (system.in); String Sendstring=scanner.nextline (); while

The socket is also called a socket, and the application usually makes a request to the network through a "socket" or answers a network request.Java has simplified the programming interface for sockets. Java provides serversocket to support it. In fact, when creating an instance object of the class and providing a port resource, a fixed location can be set up for

This is a point-to-point chat tool, is a good example of learning socket + ThreadPool. In the implementation can also learn the method delegate, event processing, window programming and so on concepts, is a more comprehensive and easy to learn examples. The code is as follows: Using System;Using System.IO;Using System.Text;Using System.Threading;Using System.Net;Using System.Net.Sockets;Using System.Drawing

1, the following is just a simple example, there is no multithreading, only one (because the scan.nextline () thread will enter the waiting state), use can be based on the specific project function to optimize processing2, the following code uses 1.8 new features, if you want to test the following code, Java version can not be less than 1.8 //Client Public Static voidMain (string[] args) {Try(Scanner
