How to kill a process in Java process.destroy ()

Question

I am tired using process.destroy (); method to kill the process. After some research, I found out that sometimes this will not work, so I tried to kill the task using the "Taskkiller".

Using this: Java tool / method for forcibly killing a child process

I run cmd through the process and I call jar through cmd (bat file). I can stop cmd through taskkill. But I could not find a way to stop the can.

EDIT:

I found a way to do this. Getting the process identifier at the beginning of the process.
