Jbutton to destroy process

[peterhammond]

i have a thread running 3 process like below...

           Process firstRun = null;
           Runtime r = Runtime.getRuntime();

           firstRun = r.exec(startRunner1.runnerStarted.toString());

           Process secondRun = null;
           Runtime r = Runtime.getRuntime();

           secondRun = r.exec(startRunner2.runner2Started.toString());

what i want with my jbutton(cancel) is to destroy all process that have started???

firstRun.destroy(); works fine

but i wont know what process it is up to when i click the cancel button, i would like to know what is running then kill it..... i.e ????.destroy();

the dirty way is i assume to list all processes and destroy them all 1 by 1

called them all the same name runProcess then killed the runProcess.destroy().
