5. Course Grades 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 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 already hold the student's score for the lab activity. Element 0 of the grades field should reference this object. set PassFailExam This method should accept a PassPailExam object as its argument. This object should already hold the student's score for the pass/fail exam. Element 1 of the grades field should reference this 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.
