You may refer to the Floating Front Design algorithm (discussed in Queue and in code) for this problem where both front and back are array indices from 0 toarray.size()-1. Q is an initially empty circular array-based QUEUE of size 8. After each statement on left has been evaluated, please enter the resulting values of thefront and back on right (HINT: please refrain from guessing based on intuition and, instead, reference code in your Queue lecture for insight):ArrayQueue Q = new ArrayQueue (8);Q.enqueue("P");char x = Q. dequeue();Q.enqueue("C");Q.enqueue("c");Q.enqueue("C");Q.peek();Q. dequeue();front =front =frontfront =front =frontfrontfront =; back =; back =; back =; back; back; back =; back =; back =

A queue is defined as a linear data structure with open ends and the operations that are performed…

Create a for-each loop that outputs all elements in the role collection of Student objects. What is necessary for that loop to function?
b. Write out the order of elements that are contained in a queue after the following operations are performed. myQueue.enqueue(new Integer(16)); myQueue.enqueue(new Integer(12)); Integer num1 = myQueue.dequeue(); myQueue.enqueue(new Integer(6)); myQueue.enqueue(new Integer(8)); myQueue.enqueue(new Integer(30)); myQueue.enqueue(new Integer(24)); myQueue.enqueue(new Integer(18)); myQueue.dequeue(); myQueue.dequeue(); myQueue.dequeue(); myQueue.enqueue(new Integer(38); Show how step by step process of arriving at your answer.
True or false: a) We can use memory maps with LinkedLists. b) If all of the JUnit tests pass, the program is guaranteed to always work.
You will create two programs. The first one will use the data structure Stack and the other program will use the data structure Queue. Keep in mind that you should already know from your video and free textbook that Java uses a LinkedList integration for Queue. Stack Program Create a deck of cards using an array (Array size 15). Each card is an object. So you will have to create a Card class that has a value (1 - 10, Jack, Queen, King, Ace) and suit (clubs, diamonds, heart, spade). You will create a stack and randomly pick a card from the deck to put be pushed onto the stack. You will repeat this 5 times. Then you will take cards off the top of the stack (pop) and reveal the values of the cards in the output. As a challenge, you may have the user guess the value and suit of the card at the bottom of the stack. Queue Program There is a new concert coming to town. This concert is popular and has a long line. The line uses the data structure Queue. The people in the line are objects…
Problem 7: Assume that a queue class called XQueue has a no argument constructor, an enqueue() method, a dequeue() method and an isEmpty() method. Write a method that merges two given queues by copying the elements in an alternating sequence and returning the resulting combined queue. Note: make sure that you don't include unnecessary spaces in your answer! public XQueue merge(XQueue q1, XQueue q2) { XQueue neWQueue = new XQueue(); while (!q1.isEmpty() && !q2.isEmpty()) { newQueue.enqueue( #01 ); newQueue.enqueue( #02); } while (!q1.isEmpty()) { #03 ; } while (!q2.is Empty()) { #04 ; } return newQueue (); }
