Question
In Java,
The following is a class definition of a linked list Node:
class Node
{
int info;
Node next;
}
Assume that head references a linked list and stores in order, the int values 5, 2 and 9. Show the instructions needed to move the value 2 in front of the value 5 so that the list is now 2, 5 and 9.

- 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 () {…arrow_forwardA queue and a deque data structure are related concepts. Deque is an acronym meaning "double-ended queue." With a deque, you may insert, remove, or view from either end of the queue, which distinguishes it from the other two.

Practice with use of Java exceptions. Practice use of generics. You have been provided with java code for SomeList<T> class. This code is for a general linked list implementation where the elements are not ordered. For this assignment you will modify the code provided to create a SortedList<T> class that will maintain elements in a linked list in ascending order and allow the removal of objects from both the front and back. You will be required to add methods for inserting an object in order (InsertInorder) and removing an object from the front or back. You will write a test program, ListTest, that inserts 25 random integers, between 0 and 100, into the linked list resulting in an in-order list. Your code to remove an object must include the exception NoSuchElementException. Demonstrate your code by displaying the ordered linked list and…arrow_forward
