I plug my controller in and somehow it didn't work

I'm sure that there is an option for me to decide for myself if I want to play with a controller since that's why controllers were invented for people to decide if they want to play on a keyboard or on a controller. I know it sounds crazy and impossible but when I plugged in my controller and tried to use it nothing happened. what's even more crazy is that its 2021 and java apparently has no controller support. I know that everyone has their own preference when playing and it being a preference it should also be an option. MEANING that when I plug my controller into my pc I expect their to be an option in the controller settings for it. hope you fix the bug ,thanks
