please those two easy parts
1- Write a method called add() that takes a linked list of integers along an integer and adds that integer to the list.
2- Write a method called print() that takes a linked list of integers and prints all its elements.
Step by step
Solved in 2 steps
- Complete the method printSkipper below. Use a loop to print every other element of a linked list parameter words. Print a space after every word and a newline after all elements have been printed. For example, if the list contains the strings "A", "B", and "C", print A C import java.util.Iterator;import java.util.LinkedList; public class Lists{ public static void printSkipper(LinkedList<String> words) { Iterator<String> iter = words.iterator(); //code here System.out.println(); }}I need to add an item to a linked list using a method. its an object consisting of a name, int, double, double, int. public static Person addPerson (Person head, Person toAdd, int position) { }1- A new static method with one parameter which is a head node for a linked list of integers, the method should create a new linked list which is equivalent to the original list of integers but with all repetitions removed, the method's return value is a head reference for the new list. this is what I have but it's not removing repetitions. public static IntLinkedBag removeRepetition (IntLinkedBag b1) { IntNode next; IntNode head = null; LinkedList<Integer> s = new LinkedList<>(); IntNode new_list = new IntNode(0, null); IntNode now = head; IntNode prev = new_list; while (now!= null) { int x = now.data; if (s.contains(x)) { new_list = new_list.next; } else { s.add(x); new_list.next = new IntNode(x, now); new_list = new_list.next; } now = now.next; } return b1; } }…
- In java, how do I implement the following methods into a linkedlist class. 1) removeLast() – remove the last number of the list 2) removeLeast()- remove least number in the list 3) removeMax()- remove largest number in the list 4) removeFirst() – remove the first number of the list 5) addNum()- add another number to the listJava Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Second image is ItemNodeSometimes a number is the same when you read it from front to back and from back to front. Two easy examples are 123321 and 891232198. Write a Method Called makePalindrome() that will return a linked list with a palindrome of the calling list. Example [1,2,3] must return [1,2,3,3,2,1] and [8,9,1,4] must return [8,9,1,4,4,1,9,8]. In Java
- Sometimes a number is the same when you read it from front to back and from back to front. Two easy examples are 123321 and 891232198. Write a Method Called makePalindrome() that will return a linked list with a palindrome of the calling list. Example [1,2,3] must return [1,2,3,3,2,1] and [8,9,1,4] must return [8,9,1,4,4,1,9,8]. In Java write a test programSometimes a number is the same when you read it from front to back and from back to front. Two easy examples are 123321 and 891232198. Write a Method Called makePalindrome() that will return a linked list with a palindrome of the calling list. Example [1,2,3] must return [1,2,3,3,2,1] and [8,9,1,4] must return [8,9,1,4,4,1,9,8]. Need the MyLinkedList.java with the new method and the test program's .java file.create a class called Dwarf that has a name (String) and a height (int). In addition, when Dwarfs are placed in a LinkedList and sorted, they will be sorted from tallest to shortest. import java.util.*; public class Main{ public static void main(String[] args) { ArrayList<Dwarf> l = new ArrayList<Dwarf>(); l.add(new Dwarf("Sleepy", 14)); l.add(new Dwarf("Dopey", 17)); l.add(new Dwarf("Doc", 9)); l.add(new Dwarf("Happy", 22)); l.add(new Dwarf("Sneezy", 29)); l.add(new Dwarf("Bashful", 11)); l.add(new Dwarf("Grumpy", 4)); Collections.sort(l); for (Dwarf d : l) System.out.println(d.getName()); }} output Sneezy Happy Dopey Sleepy Bashful Doc Grumpy
- Trying this again since part of my question keeps disappearing Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts public class ItemNode { private String item; private ItemNode nextNodeRef; // Reference to the next node public ItemNode() { item = ""; nextNodeRef = null; } // Constructor public ItemNode(String itemInit) { this.item = itemInit; this.nextNodeRef = null; } // Constructor…Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Nodes. Complete the code for the removeFirst method, which should remove and return the first element in the linked list. Throw a NoSuchElementException if the method is invoked on an empty list. Use the LinkedListRunner class’s main method to test your code. import java.util.NoSuchElementException;public class LinkedList{ private Node first; public LinkedList() { first = null; } public Object getFirst() { if (first == null) { throw new NoSuchElementException(); } return first.data; } public void addFirst(Object element) { Node aNode = new Node(); aNode.data = element; aNode.next = first; first = aNode; } public Object removeFirst() { // put your code here } public String toString() { String temp = ""; Node current = first; while (current != null) { temp =…Implement an instance method, called getFirstHalf, that belongs to yourThingLinkedBag. The method returns as output a linked list that includes allvalues in the first half of the bag's linked list. For example, for the following bag3-->5-->8-->9. the method returns 3-->5.If the bag includes an odd number of nodes, then the middle element belongs tothe first half and is included in the output.Make sure to include the methodheader. The bag should remain unchanged (i.e., do not remove the returnedvalues from the bag).
