I am developing a video media player using Java (using NetBeans). I am having a problem to keep my screen on, while the video is playing. Each time I play a video using my video player, the computer screen goes black after 15 min, while I am watching the video. How to keep it awake?

Schedueling your mouse to move programatically can do the trick.

    TimerTask task = new TimerTask() {
        @Override
        public void run() {
            try {
                java.awt.Robot robot = new java.awt.Robot();
                robot.mouseMove(0, 0);
                robot.mouseMove(1, 1);
            } catch (AWTException e) {
                e.printStackTrace();
            }
        }
    };

    Timer timer = new Timer();
    timer.scheduleAtFixedRate(task, 0, 900000); //move every 15 mins

  • Robot hal = new Robot(); while(true){ hal.delay(1000 * 30); Point pObj = MouseInfo.getPointerInfo().getLocation(); System.out.println(pObj.toString() + "x>>" + pObj.x + " y>>" + pObj.y); hal.mouseMove(pObj.x + 1, pObj.y + 1); hal.mouseMove(pObj.x - 1, pObj.y - 1); pObj = MouseInfo.getPointerInfo().getLocation(); System.out.println(pObj.toString() + "x>>" + pObj.x + " y>>" + pObj.y); } – e.erick Aug 26 '17 at 15:42
