TCP Connection The foundation of TCP is Socket. In the TCP connection, we will use ServerSocket and Socket. After the client and server establish a connection, the rest is basically the control of I/O. Let's first look at a simple TCP communication, which is divided into the client and the server. The client code is as follows: Copy codeThe Code is as follows: a simple TCP client Import java.net .*; Import java. io .*; Public class SimpleTcpClient { Public static void main (String [] args) thro
