Hello, I've been wanting to create a chat system for a while. A friend gave me part of his server (1GB RAM, 1 core). I wanted to ask if it's possible and how I should get started.
thanks and regards

It's already in power saving mode. I've had the phone since March 24th. Why does the battery drain so quickly in some places, and why does the iPhone 15 break so quickly? I have to charge it once a day; before that, it was every two days or so. I hate it.
Hello, does anyone know how I can convert a voice message from Instagram into an mp3 file so that I can transfer it to a flash drive?
I would buy it once for university, but is it worth it? 2. How long does this one-time subscription last? Until GoodNotes 7 is released?
With Java you can also create a chat program.
A planning phase (as usual) would not be wrong for the start. First, remember how your program can be described: What features are there, where should the program run, how does the surface look, etc. Ermittle builds on the necessary components as well as their structure (in which way they hang together) and see what resources you need. If a chat history is to be stored, for example, a database would be practical.
I would probably choose a web-based solution. You could use Spring or JakartaEE for the backend. Webclients could communicate with the server via WebSockets. You could either work with Vaadin, a JS-framework like React, Vue, or you’ll leave it with VanillaScript. You could create a desktop client well with JavaFX.
Yeah, that’s all right, you’d have to deal with sockets. I also think this is a good start-up project, unlike FaTech, as long as you’re looking at the internal network. I’ve done all this in C# that went with a few hundred lines of code and I’ve learned a lot.
I would create a task for the first version of two Java programs:
Create a server and a client.
The client should have three arguments: server IP, server port and username.
The client must be able to connect to the server via the ip and port and send messages via a socket and receive a socket.
The server must receive the different clients and distribute the messages sent to all chatroom clients via their usernames.
Things like connection termination etc. can be installed in the next versions.
I would not mix different programming languages, but would do everything in Java first. The learned one can later apply to everything possible.
Yeah, it’s possible. I just wouldn’t use Java for it, but the decision is with you. If you want to use Java, do that. For your project, NodeJS would probably be enough and I would recommend that. Maybe with TypeScript instead of JS. It also seems that you don’t have so much experience so far, which is why I advise you to program a little bit like that before you look at that. What you need to know is databases, network technologies (TCP / UDP) → Abstracting techniques, such as WebSocket etc. and how to program in general. The problem I see, you don’t know where to start. That’s bad. Maybe start with a smaller project to learn before you start with something big. I’m not saying you’re supposed to reject the project. No way. Just start and experiment with something else.
