Minecraft creative servers tend to focus on the building aspects of the game, allowing players to freely construct anything they desire alongside hundreds of other gamers.

In Minecraft Java Edition, players can either jump into a world on their own and explore it, or they can join their friends in a multiplayer world and play together.

This means that Java players can only play with other Java players, and the same goes for Bedrock. In order to play with friends on Java Edition, you'll need to be part of a server.
