PART C Design an essay Class that extends the Graded Activity class. The Essay class should determine the grade a student receives for an essay. The student's essay score can be up to 100 and is determined in the following manner: Grammar: 30 points Spelling: 20 points Correct Length:20 points Content:20 points. PART D 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. Write a class named CourseGrades that extends the GradedActivity class. The class should have a GradedActivity array named grades as a field. The array should have three elements, one for each of the assignments previously described. The class should have the following methods: setLab: This method should accept a Graded Activity 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. setPassFailExam: This method should accept a PassFailExam 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. This object should already hold the student's score for the essay. Element 2 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.
