One of approaches is :

class Timer {
            private static final ScheduledExecutorService scheduledThreadPoolExecutor = Executors.newScheduledThreadPool(10);
    
            private static void doPause(int ms) {
                try {
                    scheduledThreadPoolExecutor.schedule(() -> {
                    }, ms, TimeUnit.MILLISECONDS).get();
                } catch (Exception e) {
                    throw new RuntimeException();
                }
            }
        }

and then you can use Timer.doPause(50) where you need.
