Background: El Paso Packaging and Supply Co. comes back to you (again). They are very happy with your linked list based program. They would like to add more linked list functionality in the program. As you know from Lab Assignment 4, an input file may look like the following one. 20 10 8 4.5 8.45 12.2 8.0 2.5 4.0 1.0 15.0 18.0 3.5 3.5 3.5 6.0 5.0 10.0 Each line contains the width, height and length of a box. The dimensions are separated by spaces. In Lab Assignment 4. you created your own linked list; you were not allowed to use any java.util lists for this revised software. The same conditions apply for this new assignment. Assignment: All the following conditions from the previous assignment are valid in this assignment. You will not make any change to the Box class. 1. You are allowed to keep only the next variable public. The rest of the status variables of the Box class must be private. 2. Write no more than two constructors. 3. The Box class must have a public method named getVolume () that will return the volume of the box. 4. The Box class must have a public method named iscube ) that will return true if the box is cubic, false otherwise. 5- The Box class must NOT contain any main method. Feel free to write any additional method in the Box class, as you see fit. In this assignment, you will write two additional java files LinkedList.java and Runner.java. Notice that in the previous assignment you coded all the linked list operations, including iteration of the linked list, in the Runner.java file. In the new assignment, you will write the basic linked list operations in the LinkedList.java file. You will use a LinkedList object in the Runner.java file as your linked list. The skeleton of LinkedList.java is provided below
