Can somebody help with this problem (modifying & overloading)

[ryann18]

- Modify the Student class presented in this chapter as follows. Each student object should also contain the scores for three tests. Provide a constructor that sets all instance values based on parameter values. Overload the constructor such that each test score is assumed to initially be zero. Provide a method called setTestScore that accepts two parameters: the test number (1 through 3) and the score. Also provide a method called getTestScore that accepts the test number and returns the appropriate score. Provide a method called average that computes and returns the average test score for this student. Modify the toString method such that the test scores and average are included in the description of the student. Modify the driver class main method to exercise the new Student methods.

- Design and implement a class called Course that represents a course taken at a school. A course object should keep track of up to five students, as represented by the modified Student class from #2. The constructor of the Course class should accept only the name of the course. Provide a method called addStudent that accepts one Student parameter (the Course object should keep track of how many valid students have been added to the course). Provide a method called average that computed 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 roll, and prints the overall course test average.
