Does Windows 10 need Java?

Java just allows you to run software written in Java, and you may be surprised by how few websites and programs actually require Java, since almost all of them use JavaScript. If you still do wish to install it though (for whatever reason), just pick the same version (32 or 64 bit) as your operating system.

Do you need Java for Optifine?

Do you need java to download optifine. Any jar file needs java to run. So you'll need it to run optifine's installer but not if you're just using it with forge (you drop the unopened jar file in the mods folder if you're doing it the forge way). Any minecraft mod with an installer will need java.
