instance continues running even after being closed by a thread

Question

Good even after closing my instance it keeps running because of a thread I created to call a while:

public void nativeKeyPressed(NativeKeyEvent event) {
        System.out.println("Key Pressed: " + NativeKeyEvent.getKeyText(event.getKeyCode()));
        if (event.getKeyCode() == NativeKeyEvent.VC_BACKQUOTE) {
            keepPressingO = true;
            new Thread() {
                @Override
                public void run() {
                    try {
                        while (keepPressingO) {
                             Robot robot = new Robot();
                             robot.keyPress(KeyEvent.VK_Q);
                             Thread.sleep(26);
                             robot.keyRelease(KeyEvent.VK_Q);
                             robot.keyPress(KeyEvent.VK_W);
                             Thread.sleep(16);
                             robot.keyRelease(KeyEvent.VK_W);
                             robot.keyPress(KeyEvent.VK_E);
                             Thread.sleep(26);
                             robot.keyRelease(KeyEvent.VK_E);
                        }

                    } catch (AWTException e) {
                        e.printStackTrace();
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                }
            }.start();

        }

        if (event.getKeyCode() == NativeKeyEvent.VC_ENTER) {
            keepPressingO = false;
        }

    }

Could someone help me as I resolve this situation? How could I thread her to sleep when she left the while ( and if she went back to if she would wake up?)

And how could I call that thread inside a windowClosing to kill her?

Answer 1

tries to create this thread outside that scope it in the class variable declaration, and finally to finish it try the Join method().
