How can a Java program get its own process ID?

Question

How do I get the id of my Java process?

I know there are several platform-dependent hacks, but I would prefer a more generic solution.

Answer 1

In Scala:

import sys.process._
val pid: Long = Seq("sh", "-c", "echo $PPID").!!.trim.toLong

This should give you a workaround on Unix systems until Java 9 will be released. (I know, the question was about Java, but since there is no equivalent question for Scala, I wanted to leave this for Scala users who might stumble into the same question.)
