Consider java for fixing this code please: what i need is to insert method to be added ( please don't change the test class and any giving value in the first class ) here is the correct out put: ------------------testAddLast()---- {A} {A->B} {A->B->null} {A->B->null->C} ----------------------------- --------testSubListOfSmallerValues()---------- {} {B->B->B->A} {F->B->B->B->A->D} {F->B->B->G->B->A->M->D} ----------------------------- ------------Test lastIndexOf()----- -1 3 -1 -1 0 5 2 ----------------------------- ---------testRetainAll()--------- {} {6:Tony->6:Tony} {null->bad->null} ----------------------------- ---------------Test removeStartingAtBack--- false true {apple->null->bad->null} true {apple->null->bad} {2:Morning->3:Abby->4:Tim->5:Tom->6:Tony} ----------------------------- ---------test insertionSort()--------- {} {D} {D->E->E->F->G}...
For some reason I am getting errors in this code. It is saying that the variables are not visible. I will be providing one of the methods as well as the Node class. This is for a Linked list in Java. Here is the method giving me errors saying "the field Node<E>.item is not visible" as well as "Node<E>.next is not visible. public void addFirst(E e) { // adds element e to the front of the list ...
Data Structures - Singly Linked Lists You will add a method swapNodes to SinglyLinkedList class (below). This method should swap two nodes node1 and node2 (and not just their contents) given references only to node1 and node2. The new method should check if node1 and node2 are the same node, etc. Write the main method to test the swapNodes method. You may need to traverse the list. package linkedlists; public class SinglyLinkedList<E> implements Cloneable { // ---------------- nested Node class...
Here is the IntegerLinkedList_incomplete class: public class IntegerLinkedList { static class Node { /** The element stored at this node */ private int element; // reference to the element stored at this node /** A reference to the subsequent node in the list */ private Node next; // reference to the subsequent node in the list /** * Creates a node with the given element and next node. * * @param e the element to be stored * @param n...
In java Write a method public void printReverse() that prints the elements of a doubly linked list in reverse. Write a method public void delete5FromTheEnd() which deletes the 5th element from end of the list. Note that if you reach the end then you have to reverse the direction of counting. In the main() method of the test class, create a randomly generated Doubly-Linked list of 10 Integers. Next, call the delete5FromTheEnd() method and print the lists iteratively until the...

could somone please help me to complete this ! public class MyLinkedList<AnyType> { private Node<AnyType> head, tail; private int size; public MyLinkedList() { this.head = null; this.tail = null; this.size = 0; } //1.Insert a node at the end of the list public void insert(AnyType data) { Node<AnyType> newNode = new Node(); newNode.data = data; if (head == null) { head = newNode; tail = newNode; head.next = null; tail.next = null; } else { tail.next = newNode; tail =...
solve this Q in java languege Write a method that return DoublyLinkedList as reversed string For example: If the elements of a list is 1, 2, 3, 4, 5, 6 the reverse string should be 6, 5, 4, 3, 2, 1 implement reverse method you have two steps: 1- you should start traversing from the last element of DoublyLinkedList (the previous of the trailer) 2- you should add the element inside each node to string don't forget the space in...
