Transcribed Image Text:PART A
The following UML diagram indicates the different classes and the inheritance structure used. Using
this as a guide develop a program that demonstrates the working of this UML Diagram.
1) The Graded Activity Class
The getGrade() - works on the table given below.
Score
90
80
70
60
<60
Grade
A
B
C
D
F
GradedActivity
-score: double
+ setScore(s: double): void
+ getScore(): double
+ getGrade(): char
A
PassFailActivity
-minPassingScore: double
+ PassFailActivity (mps: double)
+ getGrade(): char
4
2) PassFailActivity Class - This class holds a numeric score and
determines whether the score is passing or failing.
The getGrade() method returns a letter grade determined from
the score field. This method overrides the superclass method.
3) PassFailExam Class - This class determines a passing or failing
grade for an exam.
The constructor sets the number of questions, the number of
questions missed, and the minimum passing score.
Calculate the points for each question and the numeric score for
this exam.
pointsEach 100.0 / questions;
numericScore = 100.0 - (missed* pointsEach)
The main class should consists of objects to test the various methods in the classes given.
PART B
Add 2 additional methods to the PassFailExam class
public boolean equals(GradedActivity g)
PassFailExam
-numQuestions: int
-points Each: double
-numMissed: int
+ PassFail Exam(questions: int,
missed: int,
minPassing: double)
+ getPointsEach(): double
+getNumMissed(): int
public boolean greater (Graded Activity g)
Using two objects of the PassFailExam class compare whether the exam scores are equal or greater
