Objective This assignment will help you understand how to use the Linkedlist class and the ListIterator interface in the Java Collections Framework. A palindrome is a word, phrase, number or other sequence of objects that has the property of reading the same in either direction (the adjustment of punctuation and spaces between words is generally permitted). The word "palindrome" comes from the Greek tliv (palin) "back" and Spuos (dromos) "way, direction". For example, the following is a palindrome: ABADABA. In this assignment, we solve the palindrome recognition problem. Program assignment Develop and test a program to recognize if a sequence of MyVector objects (defined in Project 1) is a palindrome, i.e. is the same from right to left as from left to right. . . Design specifications Create a Java project project 4 and a package package4. Design a driver class which will have a method to recognize a palindrome. Your sequence should be input from a file and then stored in a LinkedList object. Use two ListIterator objects, initially positioned one at the beginning, the other at the end of your linked list. One iterator should advance, the other should retreat. The program should print the result: Palindrome or Not palindrome
