How can i connect imagine a Qt interface(C++) with a logic in java. I feel like I've should know this already but I don't, I know there are API but I don't want to do it,

More context: They told me to write an aplication, game such as 4 connect, battleship or that kind of games, so I've thought to make the "snakes and ladders", i knew how i could do the 2 thinks separately but I don't know how to connect the frontend with backend, even tho I knew the games should works with threads. So I don't know if I could do it with the interface in Qt, because the main porpouse of the practice is to work with threads

i second the comment that you need to consider why you want to do this. You generally need a pretty good reason to split your codebase into multiple languages.

As far as actually doing it, you have a ton of different options, some of which have been mentioned here. Some i can think of off the top of my head:

create a library (dll or so file or the like)
set up a web server and use communication protocols (either web socket or rest API or the like)
use a 3rd party communication/messaging framework like MQ or kafka or something
create your own method of communication. Something like reading and writing to a file on disk, or a database and acting on the information plopped in

basically every approach is going to require you to come up with some sort of API that the two work together through, though, an API in the generic sense is basically a shared contract two disconnected pieces of code use to communicate.
