Minecraft server java edition?

Where can I get the right file from which I can play on the server I have downloaded various files but no servers are loaded want to pay for the server is enough if I pay for the full version

can someone give me a link where i can download server without having to pay for it and without registering for it

I don't really understand your question. With the Java Edition you have to find a server on which you want to play. There are server lists on the Internet. One of the best known should be https://minecraft-server.eu/.
