Process Overview The basic principle of network communication between client and server is as follows. Message oriented middleware may be added to a more complex architecture. For the server, the communication process is as follows: 1,call socket Function create listener socket 2,call bind Function will socket Bind to a IP And port nu ...

        Recently, a code scanning gun will be integrated in the project, and I will be responsible for docking. I have to say, this code scanning gun is really the most annoying I've ever seen. The first is the hardware, which needs to be assembled by yourself, and then the network cable needs to make one to connect to thei ...

Buffer can be used for both reading and writing. As follows: public class NioTest {     public static void main(String[] args) {         // Allocate cache with memory size of 10         IntBuffer buffer = IntBuffer.allocate(10);         // Write data to buffer         for (int i = 0; i < 5; ++i) {             int randomNumber = new SecureRa ...

Summary Suddenly I found that my snake was not online yet, so I made up a simple online snake program. Main Implementation Requirements The server's user link logic (main loop) and game run logic (in n threads) maintain a customer information vector s and a game information map. A match can have two users (as many as possible can expand ...
