Why does the Java JDK not set its own path after installation on Windows?

Problem:

After installing Java SE version 14.0.1 I tried to run the command java in CMD because I wanted to check if everything works as it should, but an error occurred because CMD could not find what I wanted.

I checked the system environment variable to see if the path for the Java JDK was set, but no, it was not set.

Question:

Why was the path not set by the Java JDK after installing Java SE 14.0.1?

Answer

It depens on the installator provider by the combianation of vendor and version. As far as I know the AdoptOpenJDK add the PATH variable
