collision of javafx circles

[torn crypt]

I wanted to build something that would detect collisions of JavaFX circles but my solution is only working sometimes (e.g. sometimes "COLLISION" gets printed way too often and sometimes not often enough)

the project can also be executed with gradle 8.13 (and in case anyone wonders: the wall collision after the for loop is working fine)

Lot of math in there for 2d circle collision.

You should change circle color perhaps when collision is detected instead of relying on print statement.
