QueueInterface bankLine = new LinkedQueue<>(); bankLine .enqueue("John"); bankLine .enqueue("Matthew"); String next = bankLine .dequeue(); next = bankLine .dequeue(); bankLine .enqueue("Drew"); bankLine .enqueue("Heather"); next = bankLine .dequeue(); bankLine .enqueue("David"); next = bankLine .dequeue();

Create a class named CustomerITD, the tests in this class will not be hard coded, instead, the main method creates a LinkedQueue and give the user a list of operations they can perform on the linked queue like, enqueue, dequeue, peekFront, contains, display, size, isEmpty and display. The serviceNumber for the first customer added to the queue should be a 4-digit random number and increments for each new customer. Test your ITD by adding, removing and performing other operations on the Linked Queue. On the next page, I'm showing an example of the ITD usage. This is just an example of how the ITD should look like. Remember, the Customer ITD is a separate class you have to create, you are free to add any methods to that class in order to create the ITD.
