A simple online chat function based on java socket (I)

Recently, I did a project, in which there was a demand for online web page communication. I haven't written code for a long time and my hands are rusty. So I wrote a demo to practice my hands and shared it with the programming tips platform, so as to make a record for myself and everyone.

Let's talk about the following steps:

1. Using AWT component and socket to realize a simple single client to continuously send messages to the server;

2. Combined with threads, multi client connection is realized, and the server sends messages;

3. Realize that the server forwards the client message to all clients and displays it on the client at the same time;

4. Change the window interface generated by AWT component into the interface displayed by front-end JSP or HTML, and the client implemented by java socket into the front-end technology.

Here, the simple function of the first step is realized first. The difficulty lies in:

1. Never used AWT components or Java related listening events;

2. Socket has not been used to interact between client and server for a long time, and CS structure has not been really developed.

The code to realize the function is as follows:

client:

Server:
