How can i turn this doubly linked list into a circular doubly linkedlist, using java
//Java program
public void add(linked list, int data){
//if list is empty
if(list.head==null){
Node node = new
Node(data);
node.next=node;
node.prev=node;
list.head=node;
return ;
}
Node last = list.head.prev;
Node node = new Node(data);
// Start is going to be next of new_node
node.next = list.head;
// Make new node previous of start
(list.head).prev = node;
// Make last previous of new node
node.prev = last;
// Make new node next of old last
last.next = node;
System.out.println(node.prev + " "
+ last.data);
}

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 =...
Java Programming: The following is my code: public class KWSingleLinkedList<E> { public void setSize(int size) { this.size = size; } /** Reference to list head. */ private Node<E> head = null; /** The number of items in the list */ private int size = 0; /** Add an item to the front of the list. @param item The item to be added */ public void addFirst(E...
BELOW IS THE CODE I ALREADY HAVE Linked List - Delete Modify Lab 5 and include the method to delete a node from the Linked List. In summary: 1) Add the method Delete 2) Method call to delete, with a number that IS in the list 3) Method call to delete, with a number that is NOT in the list - Be sure to include comments - Use meaningful identifier names (constants where appropriate) import java.io.*; 1/ Java program to...
Improve the speed of public T get(int i) by having it work backward from the end of the array if you attempt to get a member which is closer to the end than the start. This improvement will be tested through timing tests on large lists. The method should still return null if i is not a valid index. Code import java.util.Iterator; public class DLList<T> implements Iterable<T> { private static class Node<T> { public Node<T> prev, next;...
Doubly Linked List The assignment is to modify the below code in any way (like changing the method of a function). Time complexity is omitted. Any methods/functions below could be changed into something different. I was thinking of changing the method of getting size of list and maybe change from numbers to letters for nodes. import java.util.Scanner; /* Class Node */ class Node { protected int data; protected Node next, prev; /* Constructor */ public Node() { next = null;...
Doubly Linked List Is there a way to further modify/simplify/improve this program? I was thinking of maybe changing how to get size. I'm not sure. import java.util.Scanner; /* Class Node */ class Node { protected int data; protected Node next, prev; /* Constructor */ public Node() { next = null; prev = null; data = 0; } /* Constructor */ public Node(int d, Node n, Node p) { data = d; next = n; prev = p; } /* Function...
I am trying to make a linked list queue and I am trying to use the display method I made just to see if its working but when I run it nothing is displayed please help. Also the newPlane boolean was made just so I can randomly decide if the plane is going to join the queue or not. public class PlaneSimulation { public static void main(String[] args) { int landTime = 2; int takeoffTime = 3; int avgArrivalInterval =...

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...
c programming A linked list is a linear data structure that allows us to add and remove items from the list very quickly, by simply changing a few pointers. There are many different variations of linked lists. We have studied the doubly-linked, circular, with a dummy-header-node version of a linked list. In the class notes we studied several functions to manipulate a Linked List. For this assignment you must write the code for the following additional linked list functions: addFirst,...
