I want to write a small java app (preferably Java 8) that does the following:

1. List all processes that are currently running in Windows 10 and find a specific one (name and PID, there can be multiple running instances of the same app!), e.g. notepad.exe
2. Read this process’ command line, e.g. if you use notepad thisisatest in command prompt, then it opens a notepad window and the command line says notepad thisisatest in task manager.
3. If this info contains something specific, then I want to kill the process.

What I’ve already tested for 1. + 2.:

• Runtime.getRuntime().exec as suggested here – it lists the notepad.exe process and its PID but there doesn’t seem to be a way to also request the command line info
• ProcessHandle as suggested here (Java 9+, tested with Java 11) – it finds the notepad.exe process but the command line info (process.info().commandLine()) is empty
• jProcesses2 (Java 8, github), the first version was suggested here – this finds the right process but the info (process.command) is null

As for killing:

• jProcesses2 provides an example on the github page (changePriority(), stop(), then kill()) but that doesn’t work for some reason.
• Runtime.getRuntime().exec("taskkill /pid 1234 /f") (I got the PID with jProcesses2) works but I can’t be sure that I’m killing the right process, unless I can also get the info somehow.

1. and 3. are working but how do I accomplish 2.?
