Hello again, Michael!
Since I haven't heard back from you regards XXXXX XXXXX you are using, I am sending you the completed projects in both major IDEs. You can download the projects here:http://wikisend.com/download/315814/AllProjects.zip
Inside of this zip file, you will find four other zip files. There are two projects: The fractions project and the convert project.
I have sent you the two projects for Eclipse and the two projects for NetBeans.
Do not unzip any of the four projects. (Unzip the main file... do not unzip any of the four projects).
If you are using Eclipse, you will go to File->Import, General->Existing Project Into Workspace. Then select the browse button for "Select Archive File", and then select the zip file for the eclipse project you are importing. That will add the entire project to your workspace.
If you are using NetBeans, you will go to File->Import Project->From Zip...
Select the browse button for the zip file and select the zip file for the NetBeans project you are importing. This will also completely import the project into NetBeans.
You can then run either project. They both work and meet all of the requirements. For the Fractions project, if you would like to just have the Java files, you can get them from the fractions folder inside of the source folder.
The fractions project now has two java files. The new one is a custom exception type that extend ArithmeticException, as suggested in the assignment requirements.
I did the necessary exception handling in the conversion project to get you the extra credit points.
Let me know if you have any questions. I'm here to help.
Please remember to rate my answer. Thank you so much and have a wonderful day!
