sercise N2. Answer the following Question: 1. Given the following class public class DoubleNode { private Object info=null; private DoubleNode next=null; private DoubleNode back=null; 2. Complete the class Double Node by adding the necessary methods. 3. Create a class my Double LinkedList similar to myLinkedList (created in the lecture). This class should have at least the following methods: inserAtEronto, removeAtFront.print and printReverso 4. Write a method that create a linked list from a double linked list using the methods available in myDouble Linkedlist and java.util.LinkedlList 5. Create a class named "Car" which has the following fields. The fields correspond to the columns in the text file except the last one. : String i. Vehicle Name ii. Engine Number : String iii. Vehicle Price : double iv. Profit : double v. Total Price : double (Total Price - Vehicle Price + Vehicle Price Profit/100) b) In Test class, write a method named showCar (my Double Linkedlist list, String Number) takes the list and Engine Number as parameters, and displays all the information of the particular car including Total Price. c) In Test class, write the main method (in Test class) to: 1. Create my Double Linked List list. 2. Read the content of the text file and for each row an instance of the class Car is created with the calculated Total Price (use array of objects) and add each instance list in b.1). 3.
