Create an Eclipse project named Lab_Project_9, then import the CPS150_Lab11.java source code file. Do not create a Main class; instead:

Download the CPS150_Lab11.java file into the src sub-folder of your project folder. Remember that if you created the project in the default location, the project folder is located in the workspace folder of your home folder (e.g.: C:\Users\doej1\workspace\Lab_Project_11).

In Eclipse's Project explorer:

Expand your project folder to display the src sub-folder.

Right-click on the src sub-folder, and select the Refresh option.

Expand the src sub-folder, and then the default package sub-folder.

Open the file CPS150_Lab11.java.

Once the source file is opened:

Open the source code and:

Add your name to the comment block immediately above public class CPS150_Lab11 (indicated by *** Replace with your name ***)

Add the code as described by (and immediately below) each of the comment blocks labeled Lab 11.1 - 11.7.
