Java Programing Design class CarInLine, with the following specifications: The class has two instance variables: arrivalTime and DepartureTime, stored as integers. Define a constructor that accepts an integer as an argument representing the arrival time, in which you set the departure time to zero, marking the beginning of a simulation. Create an appropriate set and get methods for the two instance variables. Implement a method totalTime() that returns an integer value representing the time spent in the queue, as the difference between the departure time and the arrival time. Define ten queues, simulating the functionality of the process, increasing the number of cashiers from one, and collecting the average waiting time for each scenario. Each simulation will work with the same number of cars, which is considered 100. The maximum number of cashiers/toll booths is 10. Create the queue with link-based implementation. Create each queue with the corresponding number of cashiers,...

Java Algorithm Programming Question Implement the ADT queue by using a circular linked list. Recall that this list has only an external reference to its last note. Example Output: Create a queue: isEmpty () returns true Add to queue to get Joe Jess Jim Jill Jane Jerry isEmpty () returns false Testing getFront and dequeue: Joe is at the front of the queue. Joe is removed from the front of the queue. Jess is at the front of the queue. Jess is removed from the front of the queue. Jim is at the front of the queue. Jim is removed from the front of the queue. Jill is at the front of the queue. Jill is removed from the front of the queue. Jane is at the front of the queue. Jane is removed from the front of the queue. Jerry is at the front of the queue. Jerry is removed from the front of the queue. The queue should be empty: isEmpty() returns true Add to queue to get Joe Jess Jim Testing clear: isEmpty() returns true Add to queue to get Joe Jess Jim Joe is at the front of the queue. Joe is...

Change the __str__ method of the Queue class (provided below) so that it prints each object in the queue along with its order in the queue (see sample output below). class Queue(): def __init__(self): self.queue = [] # implement with Python lists! # start of physical Python list == front of a queue # end of physical Python list == back of a queue def enqueue(self, new_obj): self.queue.append(new_obj); def dequeue(self): return self.queue.pop(0) def peek(self): return self.queue[0] def bad_luck(self): return self.queue[-1] def __str__(self): return str(self.queue) # let's try a more fun waySample output: >>> my_queue = Queue()>>> everyone = ["ESC", "ABC", "YOLO", "HTC"]>>> for initials in everyone:>>> my_queue.enqueue(initials)>>> print(my_queue)Output: 1: ESC2: ABC3: YOLO4: HTC
