Leave sample projects using jframe(swing, awt)?

Question

Java

As an example, I can say that there is a client and he sets the price and the doctor takes the order and can continue to chat. The client can also have his own personal account, just like the doctor, only the doctor can have his own news feed, other clients can like the post and leave comments, and so on. In my opinion, this is generally done on the spring.

Answer 1

In my opinion, no swing-awt-javafx is needed here at all!
A standard (spa?) frontend application is being made in javascript, typescript, react, vue, angular (further everywhere) :)))
You can also use spring or vertx as a backend. Or you can use nodejs, ruby, php, python, go.... :)
Doctor - browser and url where to go.
If you want to in Java, look at wicklets.
Near java: clojure/clojuresctipt (both front and back), groovy, scala...
All kinds of chats are attached next to separate applications, there are hundreds of them, from rabbitmq to mosqute.
