Question

Deliverables Your project files should be submitted to Web-CAT by the due date and time specified. You submit your files to the skeleton code prior to the due date (there is no late penalty for the skelcton code assignment since this project). The files you submit to skeleton code assign method bodies have at least a return statement if applicable or they may be assignment until the project due date but should try to do this be incomplete in the sense that In order to avoid a late penalty for the project, you must submit your completed code files to it is ungraded for ment may essentially completed Web-CAT no later than 11:59 PM on the due date for the completed code. If you are unable to submit via Web-CAT, you should e-mail your project Java files in a zip file to your TA before the deadline. Files to submit to Web-CAT (all three files mu st be submitted together): . Dodecahedron,java DodecahedronList. java . DodecahedronListMenuApp.java Specifications Overview: You will write a program this week that is composed of three classes: the first class defines Dodecahedron objects, the second class defines DodecahedronList objects, and the third, DodecahedronListMenuApp, presents a menu to the user with eight options and implements these: (1 read input file (which creates a DodecahedronList object), (2) print report, (3) print summary, (4) add a Dodecahedron object to the DodecahedronList object, (5) delete a Dodecahedron object from the DodecahedronList object, (6) find a Dodecahedron object in the DodecahedronList object, (7) Edit a Dodecahedron in the DodecahedronList object, and (8) quit the program. [You should create a nevw "Project 6" folder and copy your Project 5 files (Dodecahedron,java, DodecahedronList.java, dodecahedron data 1.txt, and dodecahedron data 0.txt) to it, rather than work in the same folder as Project 5 files. A dodecahedron has 12 equal pentagonal faces, 20 vertices, and 30 edges as depicted below. The s are provided to assist you in computing return values for the respective Dodecahedron methods described in this project. Surface Area (A) Volume (V) Edge length (a) Surface/Volume ratio A/V) A 325+10y5 a 15+7,5 3

               return true;
           }
       }
       return false;
   }

}

Imoprtant Note: The format of the text file is need to be observed to implement the readFile() method correctly in DodecahedronList class. So I have put that method incomplete but the class will compile successfully but the method will not work. So you need to put the text file in another question post along with the completed codes given above. Please note that you need DodecahedronListMenuApp class which would contain the main() method to run the Project

In the limited time I was able to complete the program as much was possible. The third class i.e., DodecahedronListMenuApp has not been compeleted due to limited time and unavailability of the input text file. So please post the required part in another question. Hope you understand the issue and won't give a negative feed back.

Thank you.
