This article will teach you Java networking programming.

Java network programming involves the process of implementing network communication using the Java language, typically utilizing Socket sockets. Initially, a Socket object needs to be created and the remote host and port number specified for connection. Subsequently, data read and write operations can be carried out using InputStream and OutputStream objects.

Next, a server-side program can be created using the ServerSocket object, which listens on a specified port and accepts client connection requests. Once the connection is established, data transfer can be done through the Socket object.

In addition to basic Socket programming, Java also offers some high-level network programming APIs like URL, URLConnection, and HttpURLConnection, making it easy to perform HTTP requests, file downloads, and other operations.

In conclusion, learning Java network programming can help us better understand the principles of network communication and develop network applications. Hopefully, the above information can assist you in quickly getting started with Java network programming.
