Portable Java
TL;DR: OpenJDK JRE 64-bit and jPortable (64-bit) (for Minecraft 1.16.5 or older) are recommended.
PortableApps.com has several portable versions of Java that can be easily installed and updated from the PortableApps.com Platform. They can be found in the Utilities category and will be automatically detected by Prism Launcher Portable. The 32-bit versions are likely to crash on newer versions of Minecraft and are not recommended and the JDK versions contain extra developer tools that you likely don’t need.
