1.Following the instructions in Class Notes How Tos How to import Java source code (.java) files into a NetBeans project on this Isidore site:

i.create a new empty NetBeans project named CPS150_Lab14

ii.delete the auto-generated main class (CPS150_Lab14.java)

iii.download/import the replacement CPS150_Lab14.java source code into the project

2.Open the source code and:

i.Add your name to the comment block immediately above public class CPS150_Lab14(indicated by *** Replace with your name ***)

ii.Add the code as described by (and immediately below) each of the comment blocks labeled Lab 14.1 - 14.7.
