Course class has been provided from A3
Tasks - Graded Course Class • Task 1: The Graded Course class contains all the functionality of the Course class as it is a child class of Course class. You are given the Course class in the provided jar file named A3.jar. • Task 2: A Graded Course object can be created by giving as an argument a course name as a String, followed by the minimum score for an A letter grade, followed by the minimum score for an B letter grade, followed by the minimum score for an C letter grade, followed by the minimum score for an D letter grade. These minimum score for letter grades will be used by the countABCDFStudents() method. Complete the method public GradedCourse(String courseName, double minScore ForA, double min.ScoreForB, double minScoreForC, double minScoreForD) to complete this task. See the method comments for more detail.. • Task 3: The user can get the number of students on track for A, B, C, or D letter grades in this Graded Course. The method will return a String containing the number of students who's average of all the student's quizzes is at or better then the score that maps to the letter grades, A, B, C or D. Complete the method public String countABCDFStudents() to complete this task. See the method comments for more detail. oe.g. 1 students on track for A 4 students on track for B 7 students on track for C 2 students on track for D • Task 4: The user will be able to ask for the textual representation of this GradedCourse instance. The method will return a String in the form specified in the example below. Complete the method public String toString() to complete this task. See the method comments for more detail. Underwater Basket Weaving is a letter grade course. 1 students on track for A students on track for B 1 students on track for C 1 students on track for D Students in this course: [Bugsy 521, Daisy 321, Minny 876, Mikey 543] Test your code using the A4GradedDriver class, then submit your code on Gradescope. Fix any issues and resubmit to Gradescope as many time before the deadline as needed to maximize your score for this task. A4GradedDriver Example Output Add Student to course successfully ->true Add Student to course successfully ->true Add Student to course successfully ->true Add Student to course successfully ->true Course average for all students ->79.9075 Number of Students in the Course ->4 toString prints the following Underwater Basket Weaving is a letter grade course. 1 students on track for A 1 students on track for B 1 students on track for C 1 students on track for D Students in this course: [Bugsy 521, Daisy 321, Minny 876, Mikey 543]
