    for(int KV_COMMAND =10;KV_COMMAND < 6000;KV_COMMAND++){
            DateTimeFormatter dtf = DateTimeFormatter.ofPattern("yyyy/MM/dd HH:mm:ss");  
           LocalDateTime now = LocalDateTime.now();  
           System.out.println("KV_COMMAND "+KV_COMMAND +"\t"+ dtf.format(now));  
            robot.keyPress(KV_COMMAND);
            // robot.keyPress(KeyEvent.VK_CONTROL);
            robot.keyPress(KeyEvent.VK_S);
            robot.keyRelease(KeyEvent.VK_S);
            robot.keyRelease(KV_COMMAND);
            robot.delay(4000);
            robot.keyRelease(KeyEvent.VK_ENTER);
            robot.delay(4000);
