        //Allows executing tasks after a delay or at fixed intervals.
        //Useful for running cron jobs and monitoring!

        // Runnable run = new Runnable() {
        //     @Override
        //     public void run(){
        //         System.out.println("Scheduled Task Executed at: " + System.currentTimeMillis());
        //     }
        // };

        ScheduledExecutorService executer = Executors.newScheduledThreadPool(3);

        //4. Using ForkJoinPool (Parallel Processing)
        //Suitable for divide-and-conquer tasks, used in parallel computing.
        //Used for parallel processing (e.g., image processing, big data computations).
