Tasks/Assignments(s) 1. Create SinglyLinkedList class. Apply all the following operations as discussed in the lecture: addFirst: to add new node to the beginning of the linked list. addLast; to add new node to the end of the linked list. addNode: to add new node to a specific position in the linked list. ● removeFirst: to remove the first node in the linked list. ● ● ● ● ● findNode: to find a node with specific given value. removeNode: to remove a specific node from the list. 2. (HW) Add a Person class that holds the name and address of a person with accessor and mutator methods. Then, test the class by creating a linked list of Person objects. Add and remove objects from the linked list using linked-list operations defined in Task 1.

Lab 19 Building a linked list Start this lab with the code listed below. The LinkedList class defines the rudiments of the code needed to build a linked list of Node objects. You will first complete the code for its addFirst method. This method is passed an object that is to be added to the beginning of the list. Write code that links the passed object to the list by completing the following tasks in order:1. Create a new Node object.2. Make the data variable in the new Node object reference the object that was passed to addFirst.3. Make the next variable in the new Node object reference the object that is currently referenced in variable first.4. Make variable first reference the new Node.Test your code by running the main method in the LinkedListRunner class below. Explain, step by step, why each of the above operations is necessary. Why are the string objects in the reverse order from the way they were added? public class LinkedList{ private Node first; public LinkedList() {…

Java language the top half is the class that contains the linked list parts the bottom half is the method i need help setting up should take two parameters "index" and "element" should be an actual method not just LinkedList.set(index, element); please and thank you!
Lab 20 Removing the first element in a list 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. Java language

6. Suppose that we have defined a singly linked list class that contains a list of unique integers in ascending order. Create a method that merges the integers into a new list. Note the additional requirements listed below. Notes: ● . Neither this list nor other list should change. The input lists will contain id's in sorted order. However, they may contain duplicate values. For example, other list might contain id's . You should not create duplicate id's in the list. Important: this list may contain duplicate id's, and other list may also contain duplicate id's. You must ensure that the resulting list does not contain duplicates, even if the input lists do contain duplicates.

Lab 17 Using a linked list with an iterator Build a class called LinkedListRunner with a main method that instantiates a LinkedList. Add the following strings to the linked list: aaa bbb cc ddd eee fff ggg hhh iii Build a ListIterator and use it to walk sequentially through the linked list using hasNext and next, printing each string that is encountered. When you have printed all the strings in the list, use the hasPrevious and previous methods to walk backwards through the list. Along the way, examine each string and remove all the strings that begin with a vowel. When you arrive at the beginning of the list, use hasNext and next to go forward again, printing out each string that remains in the linked list.
"Chu" "Bethany" "Daryl" next ull next next head "Brandon' next The above is a LinkedList. 1. If a node with the data, "Brandon" needs to be inserted between the node of "Bethany" and the node of "Daryl", which step of the following needs to be performed first? a. Update the value of the box, next in the Node with "Bethany" first. b. Assign the value of the box, next in the Node with "Brandon" first. Describe the reason of your choice.
