Implement a Queue on a char [] array. Do not use ::Queue:: class from the STD library for this example. When you hardcode your queue look to make it work. Then update the code to make the queue circular. The user will input a string and the program will return the string with each letter in the string duplicated. Displaying correct Queue implementation. Utilize the conventional/traditional methods as needed. enqueue() / push_back() dequeue() / pop_front() Sample Execution Please input String: happy

I need help with getting started for this in Java. Codes listed below. Complete the CircularArrayQueue.java class implementation of the Queue.java interface so that it does not use a count field. This implementation must have only the following fields: DEFAULT_CAPACITY front rear queue Implement the methods enter leave front isEmpty isFull expandCapacity Write a test class to test each of the methods you implement. Queue.java public interface Queue<E> { /** * The element enters the queue at the rear. */ public void enter(E element); /** * The front element leaves the queue and is returned. * @throws java.util.NoSuchElementException if queue is empty. */ public E leave(); /** * Returns True if the queue is empty. */ public boolean isEmpty(); /** * Returns the front element without removing it. * @throws java.util.NoSuchElementException if queue is empty. */ public E front();}…
java program : Given the following method within the ArrayQueue class, what does it do ? public int Undefined(E item) { int i = front, count = 0; for ( int j = 0; j < size; j++ ) { if (! theData[i].equals(item)) count++; i = (i + 1) % capacity; } return count; } It returns the number of the elements in the queue not equal to the element at the front of the queue and, also item. It returns the number of the elements in the queue not equal to the element at the front of the queue. It returns the number of elements of the queue not equal to item. It returns the number of occurrences of item in the queue.
write a java method with followin instraction : Write a method called prioritizeQueue to give priority for vaccination for elderly persons. The method is to be in a class called VaccinationQueue and has two parameters q1 and q2 type ArrayQueue. The q1 and q2 data are of type Integer. Assume that initially q1 is not empty and q2 is empty. The method will insert from q1 those elements towards the beginning of the queue (front) q2 whose data is greater than or equal to 45 and will insert those elements whose data is less than 45 and greater than or equal to 18 towards the end (rear) of q2. Any data item less than 18 of q1 will not be inserted in q2. It returns the number of elements added to q2. Class ArrayQueue and all its methods including iterator are available for use. You can also create temporary queues. You are not allowed to use arrays or any other data structure. Example: Before method call: front rear q1: 14 25 50…
