In java , I want you to implement a Data Structure known as a Doubly-Ended-Queue. it is a “fair” data structure in that it implements a FIFO (First In First Out ) behavior. As such, it is often used to implement various wait lists in computer systems. For example, jobs waiting to use the CPU, jobs waiting for a printer, jobs waiting to be placed into RAM for execution. In short, whenever we want a fair strategy for waiting we use queues. A DEQUE (Doubly-ended-queue) is a related data structure. Although similar to a Queue, it differs in that it allows for insertions AND deletions from either end of the list (both the front and the rear). Your implementation MUST use a doubly-linked-list implementation. You may not use a static array implementation. Thus, a Deque is a List but it is one which only concerns itself with the first and last positions for any insertion or deletion. The 6 operations supported are : public void insertFront( int item ) - insert the given item (as a node) into the first position of the Deque. public void insertRear( int item ) - insert the given item (as a node) into the last position of the Deque. public int deleteFront( ) - delete and return the element stored in the first node of the Deque. public int deletRear( ) – delete and return the element stored in the last node of the Deque. public boolean isempty( ) - returns true if the Deque is currently empty or false if it is not. public void printDeque( ) - print the integers from the list, one per line, from the first element through to the last in order. Classes Your program must implement the following 3 classes. public class dequeDriver This class will contain your program’s main method. It will need to declare a deque object and process input as indicated below. Your program should prompt the user for the path of an input file. It should open the file for input and process it line by line. Each line of the input file will have one of the following forms. PR IF IR DF DR The meanings of each input is as follows: PR - print the current contents of the deque from front to rear using the printDeque( ) method of the deque object. IF - insert the given int value into the front of the deque. IR - insert the given int value into the rear of the deque. DF - delete the front value from the deque. DR – delete the rear element of the deque. Below is an example input file that your program should be able to process. PR IF 4 IF 5 IF 6 IR 7 PR DR PR DF PR The output for the input file shown above is : EMPTY DEQUE ----- Front ----- 6 5 4 7 ----- Rear ----- ----- Front ----- 6 5 4 ----- Rear ----- ----- Front ----- 5 4 ----- Rear ----- public class dequeNode This class will implement the linked nodes that will be used to implement the deque itself. It should have the following protected data members. protected dequeNode next; // next pointer to next node protected dequeNode prev; // previous pointer to previous node protected int val; // the integer value stored within the dequeNod.
