1) Push element from orignal queue to temporary queue while checking if its odd or not .
2) If its odd then push else ignore.
3) Now temporary queue contains all odd elements in reverse order.
4) Now Push the elements from temporary queue to orignal queue to get the correct order.

- Please help JavaWrite 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.Java
- only write the method - data structures in javaImplement a member method for the List ADT called removeDuplicates(). The method removes every duplicate from the list such that there is only ONE copy of each element in the list. The method also returns the number of copies it removed. For example, if L = {Joe, Bob, Joe, Ned, Bob, Ron, Ron}, a call to L.removeDuplicates modifies the list such that L = {Joe, Bob, Ned, Ron} and returns 3. import java.util.Iterator;import java.util.NoSuchElementException; public class Mock1ListWrapper { public static interface List<E> extends Iterable<E> { public int size(); public boolean isEmpty(); public boolean isMember(E e); public int firstIndexOf(E e); public int lastIndexOf(E e); public void add(E e); public void add(E e, int position); public E get(int position); public E remove(int position); public E replace(int position, E newElement); public void clear(); public Object[] toArray(); public int removeDuplicates(); } @SuppressWarnings("unchecked") public static…Write a method replace to be included in the class KWLinkedList (for doubly linked list) that accepts two parameters, searchItem and repItem of type E. The method searches for searchItem in the doubly linked list, if found then replace it with repItem and return true. If the searchItem is not found in the doubly linked list, then insert repItem at the end of the linked list and return false. Assume that the list is not empty. You can use ListIterator and its methods to search the searchItem in the list and replace it with repItem if found. Do not call any method of class KWLinkedList to add a new node at the end of the list. Method Heading: public boolean replace(E searchItem, E repItem) Example: searchItem: 15 repItem: 17 List (before method call): 9 10 15 20 4 5 6 List (after method call) : 9 10 17 20 4 5 6
- Write a static method named negListFromQueue that takes two parameters: an array-based unbounded queue of integers and an array-based unsorted list of integers. The method should move all negative integers from the queue, if any exist, into the list. Example: if the parameter queue contains: -2 -10 3 8 14 -7 After calling the method negListFromQueue, the content of queue and list became: queue: 3 8 14 list: -2 -10 -7Java Only Do Method, I will give LinkedList Implementation Write a method checkForEquality to be included in class KWLinkedList that does not have any parameter. Assume the list is having even number of nodes. The method returns true if the first half of the list is equal to the second half of the list in the reverse order, otherwise it returns false. If the list is empty, the method returns false; import java.util.NoSuchElementException;/** Implementation of the interface StackInt using a linked list. The* top element of the stack is in the first (front) node of the linked list.*/public class LinkedStack<E> implements StackInt<E>{ /** Node: inner class to create nodes for linked list based stack. */private static class Node<E>{// Data Fieldsprivate E data;private Node<E> next; // The reference to the next node. // Constructors/*** Creates a new node with a null next field.* @param dataItem The data to be stored in the node*/private Node(E dataItem){data =…Write a static method named SmallestEvenStackQueueToList that takes two parameters: an array-based unbounded queue of integers as its first parameter and an array-based bounded stack of integers as its second parameter. The method should find the smallest even integers from all corresponding values in the stack and queue and save them into an object of type ArrayUnsortedList and return this object from the method. If two corresponding elkments in the stack and queue are odd integers, then add the value -1 to the unsorted list. Assume that stack and queue have the same size. Examplel: if the queue has: 1 5 4 4 9 8 10 If the stack has: 4 3 10 9 5 20 Then the unsorted list has: 4 -1 4 4 -1 10 The stack and queue must become empty after calling the method. //-----Paste SmallestEvenStackQueueToList code below this line 2.
- Write a code in Java Write a method called inversePrint. This method gets a head of a linkedlist and Recursively print from the last item to the first one. This is a Recursive method. If Recursive is not used you will get no mark for this question Do not reverse the linkedlist, only print it in reverse example call: in the main I will call your method like: buffer = myList.head; //This is a buffer to copy the head address inversePrint(buffer); After this, the order for myList should not changed. if myList has: 1->2->3->4->5 your function should print: 5-> 4 -> 3->2->1 but if I check myList the order should still be 1->2->3->4->5 you can assume the LinkedList code for all other operations exist and if you need you can use them Do Not create a new linkedlist in inverse Hint: use recursion does this for you really easyWrite 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 70 35 45 19 10 21 q2: empty After method call: front rear q1: 14 25 50 70 35 45 19 10 21 q2: 50 70 45 25 35 19…Write a class MyArrayQueue that Inherit the ArrayBoundedQueue class show in screen shot and such that all the following methods are implemented in java: public String toString();// Creates and returns a string that correctly represents the current queue. public void remove(int count);// Removes the front count elements from the queue.// Throw QueueUnderflowException with message of "Less than count elements in queue." //if there are less than count elements in the queue. public void reQueue();// Dequeue an element from front, and enqueue the element back to rear of the queue.// Throw QueueUnderflowException with message of "No element in queue."// if there is no element in the queue. public void clear();// Clear entire queue.public void reverse();// Reverse queue content. Hint: you may use LinkedStack ADT.} public int space(); //return how many open spaces does the queue have still available.
