Java Programming

Hello.

I would like to kill a thread. For now, im doing like that:

                if (this.searchEngine.isAlive()) {
                    this.searchEngine.interrupt();
                }

But it seems it never ends the thread. I think it interrupts the thread, and lets other threads finish; then, it conintues until this.searcEngine thread ends. I would like absolutly destroy this thread and free its memory. How can i do it? I didnt find any non-deprecated solution in API.

Thank you.
