A hoverboard is a levitating board similar in shape and size to a skateboard; it is typically used for personal transportation (see https://en.wikipedia.org/wiki/Hoverboard). Although long considered fictional, there have been increasing recent attempts to create real hoverboards. Explain how the various characteristics of hoverboards as an innovation are likely to influence their rate of adoption among the general populace. (2 points).

A generic queue is a general queue storage that can store an unlimited number of objects. In this lab, you need to implement two types of the generic queue including Queue and Deque. The Java code of this module includes a class that represent Queues and was mentioned briefly during the lecture, therefore if you need to, please revisit the java code. The second special type of containers is called a Deque. A deque is a special type of queue that is double ended. It means that elements can be added to the queue at both ends and removing can be from both ends. In essence, a deque follows both a FIFO (First in, First out) and a LIFO (Last In, First Out) rules to insert/remove from/to the queue. This means that a deque can play the role of a queue and a stack at the same time. You can imagine a stack as a plate dispenser. When you add a plate, you add it to the top of the dispenser. When you remove a plate, you remove it from the top again. However, for a queue, you can imagine a queue of students waiting in line. The first student who comes into the line is the first student served and hence removed from the line. For the stack behavior of a deque, there are two main and two auxiliary methods: push(object): This method adds the object to the stack. IN other words, the object is added at the front. pop(): removes the last element that was added, from the stack. In other words, the object is removed from the front. top(): returns the element, which is at the top of the stack, without removing it. getSize(): returns the number of elements in the stack. Your job for this lab, is to complete GenericQueue, Queue and Deque class. I have written a comment, where you need to insert your code. 3.1. Class GenericQueue The names of the methods in this class explain themselves. If you need more clarification, please read the javaDoc for these methods. 3.2. Class Queue While Queue Is-A generic queue, it follows the rule of Queue data structure (FIFO), therefore all the methods should be implemented in a way that the rule is followed. This class has an instance variable that holds all the items. The rest of the methods are self- explanatory. 3.3. Class Deque The Deque class is a special type of a Queue that was explained above. So the deque acts as a queue and has additional methods that represent the stack behaviour. This class has a constructor that uses the list that contains the data. To implement the rest of the methods see their javaDoc. import java.util.*; import java.io.*; /** * This class is a GenericQueue that holds an unlimited number of * objects. It is able to remove objects and add objects. */ public class GenericQueue { // No instance variable should be defined for this class. /** * This method adds the <code> obj </code> to the GenericQueue. * @param obj is the object that is added to the GenericQueue. */ void add(Object object) { // insert your code here } /** * This method removes the object from the GenericQueue * @return returns the removed.
