I’ve recently noticed that Java (the software for running .JAR files, not Minecraft!) seems to be missing from my Steam Deck. I had it installed previously for running tools like Neoforge and Optifine, and those programs are still working fine, so I know it was there. Could it be possible that a Steam Deck update deleted Java without me realizing it?

Just a heads-up, other users have faced similar issues. If you can’t find Java anymore, it’s likely due to the reasons mentioned. Just reinstall it in your home directory to keep it safe, and you should be set for any future updates!
Yeah, this actually can happen! SteamOS makes changes to the root filesystem during updates, so if Java was installed there, it would get wiped. To prevent this, try installing Java in a directory like your home folder where it won’t get deleted during updates. You can check out a guide online on how to set that up!
Also, if you’re mainly using it for Minecraft, you could consider using the Prism Launcher flatpak from the Discover store since it comes with Java included. It’s a super neat solution!
