I'm playing on pc. I'm not sure how to tell if it's java or bedrock though. Does the fact that it requires a port mean that it's bedrock?

I am completely new to this, and have never even played minecraft on pc before. I have no idea why I can't get onto the server. I have managed to find the server address and name, so I think my problem is that I don't know what to put for the port. If anyone knows that it would be very helpful.
