 Q:

A multi-threaded version of TaskScheduler such that it guarantees that higher priority task never starts execution after a lower priority task in java

I need to write a multi threaded version of TaskSchedular 
TaskScheduler {
   TaskScheduler(List<Task> tasks)
   .... 
}

   interface Task {
      int getPriority()
      void execute()
    }

so that it guarantees the higher priority task never starts execution after lower priority.
Here is my single threaded version example. I need to create this multi threaded.
public class SingleThreadedTaskScheduler {

    private ExecutorService executorService = Executors.newFixedThreadPool(1);

    private PriorityQueue<Task> taskQueue;
    private static final PriorityComparator PRIORITY_COMPARATOR = new PriorityComparator();

    public SingleThreadedTaskScheduler(List<Task> tasks){
        this.taskQueue = new PriorityQueue<Task>(tasks.size(), PRIORITY_COMPARATOR);
        this.taskQueue.addAll(tasks);
    }

    public void executeAllByPriority(){
        executorService.submit(new Runnable() {
            @Override
            public void run() {
                for (Task task : taskQueue) {
                    task.execute();
                }
            }
        });

    }

    public void executeAllByPriorityWithUnInterruptableFirst(){
        executorService.submit(new Runnable() {
            @Override
            public void run() {
                PriorityQueue<Task> interruptedQueue = new PriorityQueue<Task>(taskQueue.size(),PRIORITY_COMPARATOR);
                for (Task task : taskQueue) {
                    if (task instanceof Interruptible && ((Interruptible) task).isInterrupted() ){
                        interruptedQueue.add(task);
                    } else {
                        task.execute();
                    }
                }

                for (Task task : interruptedQueue ){
                    task.execute();
                }
            }
        });

    }

    @Override
