In Java please, These are instance methods which modify the linked list ,* accessed through the instance variable: first * Note that this list keeps track of the number of elements in the instance varible N * It is important that N accurately reflect the length of the list.
* You may not add any fields to the node or list classes.
* You may not add any methods to the node class.

Q) Modify the class Linked List below to make it a Doubly Linked List. Name your class DoublyLinkedList. Add a method addEnd to add an integer at the end of the list and a method displayInReverse to print the list backwards. void addEnd(int x): create this method to add x to the end of the list. void displayInReverse(): create this method to display the list elements from the last item to the first one. Create a main() function to test...
n JAVA, students will create a linked list structure that will be used to support a role playing game. The linked list will represent the main character inventory. The setting is a main character archeologist that is traveling around the jungle in search of an ancient tomb. The user can add items in inventory by priority as they travel around (pickup, buy, find), drop items when their bag is full, and use items (eat, spend, use), view their inventory as...
iImplement a Singly Linked List detectLoop in Java, it would check whether the linked list contains a loop. Print true if yes, false if not. Test by using the following code: LL<Integer> L = new LL<>(); for (int i = 1000; i > 0; i-=3) sl.add(i); try { L.insert(122, L.getNode(70), L.getNode(21)); if (L.detectLoop()) System.out.println("True"); else System.out.println("False."); } catch(Exception e){ e.printStackTrace(); } class Linkedlist<E>{ private static class Node<E>{ private E element; private Node<E> next; public Node(E e, Node<E> n){ element =...
A(n) _______ can typically modify the values of instance variables. a. mutator method b. accessor method c. get method d. set method Choose the correct responses. static methods can be _______. a. called only from other static methods b. called only when an object has been instantiated c. accessed through a reference to any object of the class if they are public d. called when no objects of the class have been instantiated.
Given a singly-linked list interface and linked list node class, implement the singly-linked list which has the following methods in Java: 1. Implement 3 add() methods. One will add to the front (must be O(1)), one will add to the back (must be O(1)), and one will add anywhere in the list according to given index (must be O(1) for index 0 and O(n) for all other indices). They are: void addAtIndex(int index, T data), void addToFront(T data), void addToBack(T...
