Need help with my JAVA assignment, please read the note and the question carefully Thank you. Please use inheritance

Notes:

Course class:

The toString method returns the name of the course, the instructor, and the final average grade

ComputerScience class

The constructor should initialize the array of grades

The addGrade method adds new grade values up to the total number of grade values allowed

When the array of grades is full, the method calculateFinalGrade should be called to calculate and store the final grade average

The toString method should build off of the Course toString method, adding in the maximum number of grades

Write an appropriate demo class that full tests both Course and ComputerScience classes by showing a reasonable test case.

Exercise 1 Implement the following UML diagram. Note that the abstract class is indicated with italics and shading.
