The file must be called <YourNameProg2.java> (driver program)
HwScore.java (Homework Scores file)
Example: KenDeweyProg2.java (driver program)
HwScore.java is required for the HWScore file
Provide a complete program that handles the entry and display of homework scores. As part of your program, provide a HwScore class that contains the points earned on a particular homework and also the maximum possible points on that homework. In order to keep track of the overall average, the HwScore class also contains the total points earned on all homework combined and the total possible points on all homework combined. In order to determine letter grades, the HwScore class specifies cutoff values for the A, B, C, and D letter grades.
More specifically, the HwScore class should contain these constants and variables:
Named constants for the letter grade cutoffs: A = 0.9, B = 0.8, C = 0.7, D = 0.6
Class variables named totalEarnedPoints and totalPossiblePoints
Instance variables named earnedPoints and possiblePoints
YourNameProg2.java
Provide a main driver method. It should:
Instantiate four HwScore objects and store them in the variables hw1, hw2, hw3, and hw4. In the instantiations, initialize the objects to these values:
hw1: 26.5 earned points, 30 possible points
hw2: 29 earned points, 27.5 possible points
hw3: 0 earned points, 20 possible points
hw4: 16 earned points, 20 possible points
For hw1, hw2, and hw3 (but not hw4), call printGrade.
Call printOverallGrade.
HwScore.java
Within your HwScore class, include these requirements:
The HwScore class should contain a two-parameter constructor that handles initializations for the earnedPoints and possiblePoints instance variables.
Implement a printGrade method that prints a particular homework’s earned points, possible points, and letter grade. The letter grade is based on this scale: A
