Java learning simple chat example code using TCP

TCP

TCP protocol is a connection oriented transport layer protocol that ensures high reliability (no data loss, no data out of order, no data error and no repeated arrival of data).

TCP establishes a connection through three handshakes. When the communication is completed, the connection should be removed. Because TCP is connection oriented, it can only be used for end-to-end communication.

This article mainly introduces the related content of Java using TCP to realize simple chat, which can be shared for your reference and learning. I won't say much below. Let's take a look at the detailed introduction together.
