Java Web Learning Note 1: Writing a simple client/server program with a (server) socket

First, it is clear that the socket class provides the getInputStream () method and the Getoutputstream () method, respectively, to return the input stream InputStream object and the output stream OutputStream object. The program simply writes data to the data stream, sends the data to the other person, and receives data from the other party simply by reading the data from the input stream. Create a server

If the client is not responding for more than 15 minutes (900 seconds), the FTP connection times out and interrupts. at the bottom, FTP uses TCP only, not UDP.

A simple server and client program

The Example will use sockets to manipulate the server and the client in the simplest way. The whole job of the server is to wait to establish a connection and then create a inputstream and a outputstream with the socket that the connection produces. After that, everything it reads from the InputStream is fed back to OutputStream until the line abort (end) is rec
