How to make a button that, when pressed, stops the execution of the internal program?

Question

(individual question from the IDE-style program )

Answer 1

Your best bet is probably to deploy a new JVM through ProcessBuilder .

However, you can kill the internal program (and all the threads it spawned) using ThreadGroups. (I do not recommend using it). It uses the stop method, which according to the docs is " Deprecated . This method is inherently unsafe. See Thread.stop () for details." ):

 public class Main { public static void main(String args[]) throws InterruptedException { ThreadGroup internalTG = new ThreadGroup("internal"); Thread otherProcess = new Thread(internalTG, "Internal Program") { public void run() { OtherProgram.main(new String[0]); } }; System.out.println("Starting internal program..."); otherProcess.start(); Thread.sleep(1000); System.out.println("Killing internal program..."); internalTG.stop(); } } 

 class OtherProgram { public static void main(String[] arg) { for (int i = 0; i < 5; i++) new Thread() { public void run() { System.out.println("Starting..."); try { sleep(5000); } catch (InterruptedException e) { e.printStackTrace(); } System.out.println("Stopping..."); } }.start(); } } 

Output:

 Starting internal program... Starting... Starting... Starting... Starting... Starting... Killing internal program... 

Answer 2

• Run the code in a separate JVM. Use the debugger interfaces to manage this JVM.
• Set the byte code of the classes you are about to run. Paste revocation checks into the appropriate places, and grab access to the global JVM resources.

The second option is probably an endless source of annoying errors.
