In a course, a teacher gives the following tests and assignments:
• A lab activity that is observed by the teacher and assigned a numeric score.
• A pass/fail exam that has 10 questions. The minimum passing score is 70,
• An essay that is assigned a numeric score.
• A final exam that has 50 questions.


Write a class named CourseGrades. The class should have an array of GradedActivity objects as a field. The array should be named grades. The grades array should have four elements, one for each of the assignments previously described. The class should have the following methods;


setLab:

This method should accept a GradedActivity object as its argument.
This object should have already hold the student's score for the
lab activity. Element 0 of the grades field should reference this
object


setPassFailExam:

This method should accept a PassFailExan object as its argument.
This object should already hold the student's score for the pass/fail
exam. Element I of the grades field should reference the object.


setEssay:

This method should accept an Essay object as its argument, (See
Programming Challenge 4 for the Essay class. If you have not
completed Programming Challenge 4, use a GradedActivity object
instead.) This object should already hold the student's score for
the essay, Element 2 of the grades field should reference this
object.


setFinalExam:

This method should accept a FinalExam object as its argument. This object should already hold the student’s score for the final exam. Element 3 of the grades field should reference this object.


toString:
This method should return a string that contains the numeric
scores and grades for each element in the grades array

Demonstrate the class in a program.

 

 

Additional requirements:

1. Need to have proper design ( UML with Flowchart) via Dia app. Flowchart should be drawn  for each method in UML.

2. Proper comments.

3.Proper doc-string describing  each method in code.

4.Proper Documentation should be for the code.
