How to stop a process from a java application

[Yadagiri Rao KP]

Sir,
I am doing this assignment.For example if I run "ls" command in a java
application and the file contents are big and I want to stop the
process.
I know that "kill" will be a better option but this takes a pid.Am I
right? How should I know when I am running a java application the pid
of the unix command ?
Or is there any other way to stop such as --on unix machine we do "q!"
to stop a process.
Pls guide.

Hi,

If You start the process from another java process you get a reference
to a Process, which you can "kill"

Try something like:

Process p = Runtime.exec("ls");
.....
if (...) {
p.destroy();
}

Hope this helps,
