For this assignment, you will take on the role of a member of an IT department. Your chief technology officer (CTO) has tasked your department with the replacement of IT equipment. Your manager does not want to buy a piece of equipment based on the brand name alone. Rather, your manager wants to know the return on investment for each piece in order to make a sound purchasing decision.

Your task is to write a Java program that will be used to calculate ROI on three different pieces of equipment and sort it from best to least ROI. The program must prompt the user to enter the brand name of the equipment, the gain, and the cost for each piece of equipment.

In this coding assignment, you will express searching and sorting algorithms to return the ROI best to least for each piece of equipment. You must apply algorithmic design techniques in developing your program so that you can ensure the user will receive a correctly sorted list. Utilize a LinkedList class to create the list. Include comments for each section of the program. You may select variable names as long as proper Java syntax is used. You will also submit your source code in a zip file.

Utilize a Java LinkedList to input the brand name of the equipment along with the equipment’s corresponding gain and cost. The input should be completed by the user either via keyboard or via file. As a last resort, the data can be hard-coded into the program.
