“ JVM进程”是什么意思？

Question

From Java In a Nutshell

jps provides a list of all active JVM processes on the local machine (or a remote machine, if a suitable instance of jstatd is running on the remote side).

What does "JVM processes" here mean,

• processes of the underlying OS which run JVM exactly, or

• processes that are supported by Java via Process , ProcessBuilder and Runtime.exec() ...

Thanks.

Answer 1

A running Java Virtual Machine (JVM) instance is materialized by a native process launched by an OS while a Process class instance is a native process launched by a running JVM.
As each Java Virtual Machine is associated to a specific native process, instead of saying a process that runs a JVM, we could so shortcut it by a JVM process.
