Write a piece of code that prints the elements of a queue of integers, one per line.
When your code is done running, the queue should still contain the same contents as it had at the start. In other words, don’t destroy the queue as you print it. If you like, put your code into a method called print that accepts the queue as a parameter.

- Write a method called changeQueue to be considered inside the ArrayQueue class and has one parameter item of type E. Your method will change the queue in such a way that if the the first element of the queue and the last element of the queue are equal, the first and last elements in the queue will be replaced with item, otherwise, do not do any change. Similarly, the same process is done for the second element in the queue and the element before the last in the queue and so on. Assume you have a non-empty queue with even number of elements. You are not allowed to call any method from the the ArrayQueue. class. Do not use iterators. Method head: public void changeQueue(E item) Examplet: Before run: front rear "this" queue: 10 29 2 25 10 Item1: 100 After run: front rear "this" queue: 100 29 100 100 5 100 Use the editor to format your answerWrite a method that accepts two lists of integer values and checks if theyare identical or not (i.e. contain the same values). if they are not identical, the methodmust display the max value of each list.Write a method called queuesCommonCount to be included in the class queueEx that accepts two parameters q1 and q1 of type ArrayQueue. The method finds the number of elements, which are common in q1 and q2 and returns this number. Class ArrayQueue and all its methods are available for use. Use iterator to access elements of q1. Do not use any iterator to access the elements of q2. You can use a temporary queue in your method. Example: q1: 10 5 12 7 11 15 20 q2: 14 9 7 20 10 12 18 20 The method will return 4 as 4 elements, namely 10, 12, 7 and 20 of q1 and q2 are same. public class QueueEx { public static<E> int queuesCommonCount(ArrayQueue<E> q1, ArrayQueue<E> q2) { نفس

For example, if the initial list of letters is "STOP", then "TOP" and "TOPS" are both valid permutations, but "STOPS" isn't10.11 PROJ-3: Racko (Checkpoint A) In this project, you will implement the game of 'Rack-O, a game that involves rearranging your hand of cards in order to have an increasing sequence. Each card just has a number. While Racko is typically played with 2 to 4 players, we will keep this simple and just use two players. One player's moves will be decided by the user via input. We will also build a computer player whose moves are decided by you, the programmer. This game will be built in stages: Checkpoint A, and Checkpoint B, and an extra credit Checkpoint C to participate in a Racko class competition! This Idea/concept application of this project was obtained from Dr. Bhusnurmath at the University of Pennsylvania. Overview A Racko deck is composed of 60 cards, numbered 1 to 60. A hand is kept in a special place, called a rack. The objective is to be the first player to arrange all of the cards in your rack from lowest to highest. To set-up the game, we shuffle the deck and each player…
- 1. Write a method called doubleListthat takes an ArrayList of strings as a parameter and replaces every string with two of that same string. For example, if the list stores the values ["how", "are", "you?"] before the method is called, it should store the values ["how", "how", "are", "are", "you?", "you?"] after the method finishes executing.In your program1, you also need to create a class namedProgram1.java, where you are going to construct some arralylists to test the doubleList within the static void main method. In the output, it will print out the original list and the new list after calling the doubleList method. 2.Write a method called filterRange that accepts an ArrayList of integers and two integer values min and max as parameters and removes all elements whose values are in the range min through max (inclusive). For example, if a variable calledlist stores the values [4, 7, 9, 2, 7, 7, 5, 3, 5, 1, 7, 8, 6, 7], the call of filterRange(list, 5, 7);should remove all values…JAVA Create a new class HashSetManipulation with a main method. Create a new HashSet set and populate it with initial values "A", "B", and "C" using the add method. Print the size of the set using set.size(). Use a for loop to print the values in the set. Use the add method to add a new value "D" to the set and print the result of the set to show that the value has been added. Use the remove method to remove value "A" from the set and print the result of the set to show that the value has been removed. Use the contains method to check if the value "C" exists in the set and print the result.Create the Median class that has the method calculateMedian that calculates the median of the integers passed to the method. Use method overloading so that this method can accept anywhere from two to five parameters. How to calculate medianThe median can be thought of as the "middle" number in an ordered list of numbers. There are two numbers in the "middle", the median is the average of these two numbers. Method Call Return Value m.calculateMedian(3, 5, 1, 4, 2) 3.0 m.calculateMedian(8, 6, 4, 2) 5.0 m.calculateMedian(9, 3, 7) 7.0 m.calculateMedian(5, 2) 3.5 Hint Finding the median requires that the numbers be in order. You can use the method Arrays.sort(myArray); to sort an array of integers.

Say we wanted to get an iterator for an ArrayList and use it to loop over all items and print them to the console. What would the code look like for this? 5. Write a method signature for a method called foo that takes an array as an argument. The return type is void. 6. What is the difference between remove and clear in ArrayLists.A Maze Room : In this lab, we will make a maze game. The maze is based on Linked Lists. Instead of having one possible direction (next), we will have 4 possible directions. Rooms: Use the below code as a basis to build your own room class. Implement this class in the file room.py A room will be the basic object for our maze game. A room can have 4 doors (pertaining to north, south, east, and west). Attached to each these directions we have either another room or None (we could also imagine that the None doors are just walls). We want the player to be able to tell what room they are in. Each room will have a unique description. When the player enters a room, the program will describe the room. This way the player will know if they went back to a room that have already been to. You MAY NOT change the method's arguments/names in ANY way. class Room():def __init__(self, descr):#Description of the room to print out#These should be unique so the player knows where they areself.descr =…
