I've owned Minecraft bedrock edition for windows 10 for about 2 years, when trying to buy Java, I always run into the problem that I can't own more than one version of Minecraft.
Can I buy Java edition after buying Bedrock edition for windows 10?

There is no compatibility issues between Java and Bedrock editions of Minecraft on a windows computer. You may own both versions and switch between them freely on one computer. You will, however, have to pay for and download each separately.
