Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Writing TUI with Ratatouille
Most answers were a code-golf style with writing the full functionality in least number of lines of code. I took a different approach. Since some time already I wanted to try out Ratatouille - an Elixir toolkit for writing TUI (Terminal UI), based on termbox.

I looking for a TUI liberary/framework with good aesthetics.
If you want to go lower-level, then I would recommend against ncurses, and instead start with notcurses or termbox. termbox has lots of language bindings, but the author is no longer maintaining it. Still, not a bad place to start from. If you do decide to get into ncurses, this doc can get you over some of the humps with keyboard/screen/mouse.

Alternatively, there's termbox: https://github.com/nsf/termbox (minimalistic). Or prompt_toolkit: https://github.com/prompt-toolkit/python-prompt-toolkit (huge).

Textual Web: TUIs for the Web
I wrote a TUI before for work, entirely of my own volition and for my own near-exclusive consumption (it was theoretically for anyone, but I'm the only person who would've had a reason to look at it - we were a fairly silo'd dev shop).
This is what made me pick TUI over a web UI:
* no web stack, period. no client/server. no js or html. this simplified the problem dramatically. also, no additional services to babysit.
* no browser - no certificates, security, auth, etc. It's just unix permissions and ssh.
* there's something comforting about the constraints of just ASCII/ANSI and curses. No bikeshedding over border widths or radii when it's just you picking among a few characters for the shape. just having less decisions to make speeds things up and helps you focus on what you actually want the UI to be able to do.
Obviously if your app is just calling APIs anyway, that might be negate some of these bullets about no additional services to babysit etc. In this case, it was running an internal infra app that directly connected to a pg db.
And what made me pick it over just having a CLI:
* discoverability - it was a complicated app and while it was all technically exposed via cli flags, having a GUI made it a lot easier to figure out what the right incantation is.
* richer communication medium that's back-and-forth instead of unidirectional. The TUI is able to fetch a list of e.g. valid IDs and let you pick them with a check-list, instead of you having to go query the db yourself and type them in.
I consider it one of my greatest victories that my boss was able to use the TUI to recover from an incident without needing to page me while I was on holiday, and he said he barely had to read the docs and felt confident he was getting it right the first time. "I did it while sipping my coffee."
I used https://github.com/mabe02/lanterna - would recommend. They even have a Swing-based emulation mode for easy development iteration running it from intelliJ.

Textual: Rapid Application Development Framework for Python
This looks really cool.
In the past I used lanterna (https://github.com/mabe02/lanterna/tree/master) to develop a text UI for a critical process at the trading firm I worked at. It was essentially a process that would take updated market data and handle things that changed between the last trading session and today - like symbol renames (PCLN to BKNG), changes to market cap that make it change what "category" it fell into (they were based on market cap and volatility measures etc). Things of that nature, that the realtime system didn't handle but happened too often or were too hairy for us to just handle manually.
The system had a desktop UI component that was oriented towards use by our trading staff. We didn't really have notion of a "server UI" and the server was headless.
Nobody at our firm was a frontend developer, just backend, systems and data programmers who occasionally dabbled in frontend. So web UIs were very simplistic or highly specific to their use-case, we had no shared tooling.
In 2023 with things like create-react-app and whatever next.js does, I probably would've opted for one of those. I could've made another desktop app but I wanted to be able to easily get to this from a shitty ssh connection over tethered 4g when I was on-call. So X11 forwarding and RDP were out. So i looked around for a TUI-builder in the project's language, Java.
What i really liked about Lanterna was that it had a Swing-based implementation which meant I could easily run it from IntelliJ, and that would let me iterate rapidly, and then in production I could run it in a terminal via SSH directly on the machine the server was on (which had certain advantages).
I'll keep an eye on this to see if I can think of anything neat to build on it. I still generally don't like web apps because they feel like they take a lot of effort to get something compared to a functionally-equivalent product built in something non-browser-based like a TUI or desktop GUI.

What options are there for making GUIs and other visual programs using java?
Just to differ what others already mentioned: Lanterna. Pretty retro GUIs just for fun.

How to modify lines in console (Java 8)
You can use a library such as https://github.com/mabe02/lanterna to do fancy console printing. You could even do full console UIs, but just printing lines and moving the cursor and so on is also possible I think.
