Create a program to view the waiting list. The list (5 entries) is created in the program and is an object of the LinkedList class. The list entry is a QueuePerson object that contains the queue's last name, first name, and patronymic fields (of type String), an AddressValue field for the queue's address, and queue priority (int type). In turn, the field of the AddressValue type contains three fields of the String type: the name of the city, the name of the street and the house number, as well as an int type field - the apartment number (if the apartment number is 0, the house in which the subject lives does not have apartments). Entries in the queue are sorted according to priority, and the queue is added last in the queue of its priority. Provide the possibility of receiving so that there is no repetition in the queue by the name of the person on the waiting list, for which use TreeSet.
- In Javascript an array can be treated like a queue---a FIFO (first-in, first-out) data structure. Which two array operations that we studied in class can be used together to treat an array as a queue? a. isEmpty() and isFull() b. queue() and unqueue() c. unshift() and pop() d. push() and pop() e. unshift() and shift()Create the generic interface GenericQueuable<T> that contains the following abstract methods: - an abstract method insertEnd(T e) which adds the element to the Queue at end. - an abstract method removeBegin() which removes a element from the begining of the queue. - an abstract method printQueue() which prints the queue elements from the front of the queue to end. - an abstract method isQueueEmpty() which returns true if the queue is empty otherwise return false. Create GenericQueue<T> such that it implements GenericQueuable<T>.

- Hi! Currently stuck in a java problem and would appreciate the help! Question: You have probably heard about the deque (double-ended queue) data structure, which allows for efficient pushing and popping of elements from both the front and back of the queue. Depending on the implementation, it also allows for efficient random access to any index element of the queue as well. Now, we want you to bring this data structure up to the next level, the teque (triple-ended queue)! The teque supports the following four operations: push_back x: insert the element ?x into the back of the teque. push_front x: insert the element ?x into the front of the teque. push_middle x: insert the element ?x into the middle of the teque. The inserted element ?x now becomes the new middle element of the teque. If ?k is the size of the teque before the insertion, the insertion index for ?x is (?+1)/2(k+1)/2 (using 00-based indexing). get i: prints out the ?thith index element (00-based) of the teque.…A) Write a generic Java queue class (a plain queue, not a priority queue). Then, call it GenericQueue, because the JDK already has an interface called Queue. This class must be able to create a queue of objects of any reference type. Consider the GenericStack class shown below for some hints. Like the Stack class below, the GenericQueue should use an underlying ArrayList<E>. Write these methods and any others you find useful: enqueue() adds an E to the queue peek() returns a reference to the object that has been in the queue the longest, without removing it from the queue dequeue() returns the E that has been in the queue the longest, and removes it from the queue contains(T t) returns true if the queue contains at least one object that is equal to t *in the sense that calling .equals() on the object with t the parameter returns true.* Otherwise contains returns false. size() and isEmpty() are obvious.The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
- This assignment will require you to implement a generic interface (Queue<T>) with an array based queue implementation class QueueArray<T>. floating front design. Once you have implemented the class, the test program will run a client test program on the enqueue, dequeue, display and full methods. The test program will create queues of Integers as well as String objects. Enjoying the power of your generic implementation both will work with no additional changes. There are TODO based comments in the implementation file. Create a project and demonstrate that you can successfully create the required output file, shown below. Thr file includes: Queue.java package queueHw; public interface Queue <T> { public boolean empty(); public boolean full(); public boolean enqueue(T data); public T dequeue(); public void display(); } ...

It should return the value: 9
