It isn't that simple since you have to kill an independent operating system process you have just started. Looks like How to find and kill running Win-Processes from within Java? might help you.

In short: you have to find the PID of a batch script (actually, of a cmd process running your batch script) and kill it using taskkill.

If the batch is running in cmd.exe using Java, run this

Process prClose = Runtime.getRuntime().exec("taskkill /im cmd.exe");

If you run a java or javaw on your .bat file, you need to terminate your batch file first:

Runtime.getRuntime().exec("taskkill /f /im jqs.exe") ;
Runtime.getRuntime().exec("taskkill /f /im javaw.exe") ;
Runtime.getRuntime().exec("taskkill /f /im java.exe") ;

And stop cmd(if needed)

Runtime.getRuntime().exec("taskkill /f /im cmd.exe") ;

Hope this help!
