What's a good Java, curses-like, library for terminal applications?

Question

I would like to write a Java terminal application that does screen manipulation. Are there any good libraries out there that allow you to manipulate the screen like curses in the *nix/C world?

Minimal features I'm looking for are windowing and user input support.

In feature-speak, I'd like to have a region of the terminal where some data is regularly updated while (at the same time) the user can enter commands/text in some other part of the screen.

Lanterna

I found the Lanterna library recently. Haven't had the opportunity to use it yet but it looks like a more up-to-date alternative to the others.

Thanks! I was looking for one that uses no native code. – David Ehrmann Sep 20 '13 at 20:57
Last update was 4 months ago. Seems like the most recently maintained solution here. – Thomas Feb 16 '22 at 01:30
[*Griffon*](http://griffon-framework.org/) is an application framework that supports 4 different UI toolkits: Swing, JavaFX, Apache Pivot, and Lanterna. – Basil Bourque May 02 '22 at 19:00

There is Charva, which links to native code but has an api based on Swing. The screenshots show lots of text windows, so that looks useful.

Nice one, too bad though that it requires native libraries. I'll give this a shot and see how far I get. – Francisco Canedo Jan 16 '09 at 12:03

Haven't used it myself, but Java Curses Library sounds like what you want.

Sounds good, but I think I'll go with Charva, since that'll provide a more OO experience. Thanks for the suggestion. – Francisco Canedo Jan 16 '09 at 12:02

Here is a way to call the ncurses lib using JNI. I tested this and it works.

As of 2013, the closest I can find is Blacken.

Blacken is not a curses library per-se. It moves away from the terminal, and instead, renders it's own "console window." This has the disadvantage of not looking "console-like." Instead, you get full (arbitrary) colour support, and a curses-like API (in addition to their main API).

You can also set the font to Mono for fixed-width characters.

Perfect for what I was wanting to do. Thank you. – Mar 07 '14 at 06:06

@jdersen there are some bugs in Blacken, but overall, it's quite good, and the owner responds quite quickly to opened issues. – ashes999 Mar 07 '14 at 14:09
