The point is that the JVM presents a sort of 'virtual platform' to program for, and that virtual platform sits on top of the 'real' platform (Windows, Mac, etc.) and therefore the code you write is (or can be) independent from the real platform.

You also don't necessarily have to install a JVM on the platform, you can bundle the JVM as part of your application.
