Exercise #2. 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 mxDouble LinkedList similar to moxLinked List (created in the lecture). This class should have at least the following methods: inser at Fronto, removeatfronto, print, and printReverse(). Write a method that create a linked list from a double linked list using the methods available in mxDouble Linkedlist and java.util.Linkedil ist. 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. 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. i. Vehicle Name : String 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 (myDoubleLinked List list, String eNumber) 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 pox Double LinkedList 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. Test the method sbow Card) 4. Test the methods written in mx Doublelinkedlist. Exercise #2. Answer the following Question: 1.
