# LetterGrade + BahamaLetterGrade
The BahamaLetterGrade also uses the LetterGrade enumerated type, assigning its own specific ranges and values to the possible LetterGrade values.
Problem Statement
Write the code for the BahamaLetterGrade class and the LetterGrade enumeration to represent a letter grade as assigned in universities in the Bahamas. (For more information on Bahaman letter grades, see http://en.wikipedia.org/wiki/Letter_grade.) . The solution must meet the following requirements (new requirements are in green, bold italic font):
- The LetterGrade enumeration should be "generic" and support letter grades of A through F inclusive
- The BahamaLetterGrade should reject the LetterGrade of E (which is not allowed in the Bahamas) as well as any null letter grade
- The BahamaLetterGrade should get the appropriate descriptions for the grade, based on the following table:
| Grade | Grade | Value Description |
|---|---|---|
| A | 4 | A-4 - 90-100% |
| B | 3 | B-3 - 71-89% |
| C | 2 | C-2 - 56-70% |
| D | 1 | D-1 - 46-55% |
| F | 0 | F-0 - 0-45% |
