How to kill a process in Java, given a specific PID

Question

How do I kill a specific process from Java code on Windows, if I have the specific PID.

Answer 1

I don't know any other solution, apart from executing a specific Windows command like Runtime.getRuntime().exec("taskkill /F /PID 827");

Answer 2

With Java 9, we can use ProcessHandle:

ProcessHandle.of(11395).ifPresent(ProcessHandle::destroy);

where 11395 is the pid of the process you're interested in killing.

This:

• First creates an Optional<ProcessHandle> from the given pid

• And if this ProcessHandle is present, kills the process using destroy.

No import necessary as ProcessHandle is part of java.lang.

To force-kill the process, one might prefer ProcessHandle::destroyForcibly to ProcessHandle::destroy.
