Question: Write a class called Course that represents a course taken at a school. Represent each student using the modified Student class from the previous programming project. Use an ArrayList in the Course to store the students taking that course. The constructor of the Course class should accept only the name of the course. Provide a method called addStudent that accepts one Student parameter. Provide a method called average that computes and returns the average of all students' test score averages. Provide a method called roll that prints all students in the course. Create a driver class with a main method that creates a course, adds several students, prints a roll, and prints the overall course test average.
