learn socket programming in java

Learn Java socket programming in three steps Step 1: fully understand socket 1. What is socket? The so-called socket is also called "socket". It is used to describe the IP address and

OutputStream was not very clear, and it was often wrong to use the Write () method on the InputStream. I do not know where to see such a phrase, I/O flow operation is relative to the socket,serversocket connected with the data flow pipeline, reader and write is read and write meaning, is relative to that data flow pipeline operation. That is, read the information in the pipeline and write the information to the pipeline. I don't know. The last is th

#开头的废话 # To learn Java has been half a month, the original in the textbook in the word, I think the textbook is very thick, to see not know to go to the SE years. Suddenly on the Internet to see a tutorial, the teacher said that learning programming language books do not have to look too closely, to see a general, know what to say on the good, do not remember, and then you kept, hard to make up, do not unde

This article describes the Java based on TCP protocol socket programming method, share for everyone to reference. The specific analysis is as follows: The following is a one-to-one communication programming implementation that will continue to learn about the implementation of a server listening to multiple clients. The main steps used here are as follows: Fir

A simple example of a Linux Java program communicating with a C language program through a socketthis morning, I experimented with a Java program communicating with a C language program through a socket. Because did not learn Java, so just write the C language side of the co

Get socket read-write stream outputstream os=socket.getoutputstream (); PrintWriter pw=new printwriter (OS); Input stream InputStream is=socket.getinputstream (); BufferedReader br=new BufferedReader (New InputStreamReader (IS)); 3. Use the flow according to certain operation, the socket for read and write operation String sendinfo= "Send data information to the server!" "; Pw.write (sendinfo); Pw

();}} 　　 The debugging result is as follows: 　　　　 Start the server before debugging. If the client cannot find the server, it cannot run. The running effect is still very good. Fortunately, you can run it directly after writing it. The key is the correct idea. As a result, I have come up with a rule that no matter what project you want to do, you should first check the materials, understand and understand the principles of the program, and have a clear idea to ensure the success rate of the pro

network, so the TCP transmission efficiency is not as high as UDP. 2. UDP is simple and requires less monitoring, so it is usually used for client/server applications in decentralized systems with high reliability of LAN. For example, video conferencing system, does not require audio and video data is absolutely correct, as long as the consistency can be guaranteed, in this case, the obvious use of UDP is more reasonable.
