Java code is run inside a client (JRE) that provides it a non system-dependent runtime environment. If there’s a JRE for your OS, all java programs should work fine regardless of the OS.
This is the case with Minecraft, for example. When the launcher was still based on Java, you could run the Windows executables on Linux and it worked.
However, some programs might still not work on another OS despite it having a JRE. That could be caused by intentional limitations or the use of a system-specific library.
