Can someone tell me what is the difference between the two? And I think Java can only be played alone, right? I bought Java and was thinking about whether I would also like to have Bedrock, but I have no idea whether it is worth it if there's not a big difference
So Java is for the computer and Pc. Bedrock is for almost everything else. With Bedrock you can play together. With Java too, e.g. On servers. To play only with your friends, I think that unfortunately you will have to buy your own server / realm.
There's a big difference.
You can also play together in both versions.
Among other things, you have to pay for pretty much everything with the Bedrock Edition (skins, maps, textures, …)
In addition, some functions are missing (e.g. The WorldBorder)
