Grade Data

Write a class GradeData that is based on two parameters: pointsEarned and pointsPossible. The class should include a constructor that accepts those two parameters in that order, and four methods:

1. getPointsEarned() returns that value

2. getPointsPossible() returns that value

3. calculatePercentage() returns a double value as a percentage between 0 and 100

4. getLetterGrade() returns a String value based on the result calculated by the .calculatePercentage() method. Use the following percentage distribution to determine the letter grade:

   • percent >= 90 --> A
   • percent >= 80 and < 90 --> B
   • percent >= 70 and < 80 --> C
   • percent >= 60 and < 70 --> D
   • percent < 60 --> F

Write a GradeDataTester program with a main() method that demonstrates the use of the GradeData class.
