Vibrate Phone | Android Studio | Java

How to vibrate phone programmatically for a specific time?

        Button vibrateBtn = findViewById(R.id.vibrateBtn);

        //init Android Vibrator API
        vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);

                    vibrator.vibrate(VibrationEffect.createOneShot(1000, VibrationEffect.DEFAULT_AMPLITUDE));
                } else {
                    vibrator.vibrate(1000);
