Do JAVA applications use the JVM?

Do Java applications use the same JAVA virtual machine plug-in that JAVA
applets do? Or, do actual JAVA applications require the whole JAVA runtime
environment to be installed?

That's an implementation specific question. Any java code requires a VM
to execute in. Whether the vendor supplies one VM for both standalone
and applet based functions is up to them.

In Linux the applets and standalones use the same VM. the java plugin
starts up the JVM from the SDK/JRE.

In windows I don't know.

Note that java includes a control panel application to tell the plugin
where to find the JVM it uses in a web browser.

Some Java application install a JRE that they will use, some
applications use the JRE that's installed with Sun's installer.

Both ways has it advantages and disadvantages.

I don't think this is easy to do, certainly not when a program uses its
own JRE.

The solution might be in system management.
