Assume I am working on a unknown computer (from a friend/colleague) where some pre-installed Java installations exist.

When I type on a command prompt/terminal:

java -version 

the output tells me if java.exe is part of a JavaSE or JavaEE installation.
But it does NOT tell me if I use

java.exe from the jdk path/part or the jre path/part.

How can I find out (in Win) WHICH java.exe I used in detail?

Keep in mind that there could be further applications/developments tool which might bring their own
jdk/jre installation.

So java.exe could be called from these additional installations as well.
