Is the Minecraft Java edition still available for Windows 10? [duplicate]

I purchased the Java edition 6 years ago, but after some time I uninstalled it. A few weeks ago I wanted to play again. When I went to download it, I got a message that I have a free code for the Windows 10 edition, so I downloaded that edition, but I didn't like it (among other things, you couldn't press F3 to view your coordinates). Today I wanted to download the Java version again, but it seems I cannot; when I go to "Download", it says "You already own Minecraft" and I have an option to download it on Windows 10. Whatever I try, I always seem to end up with that message.

Is it still possible to play the Java edition on Windows 10?

Yes. You can download the Java edition on the Minecraft website.
