Exercise 3: GradeManager.javaj| Create a driver class Grade Manager with the main method to do the following: a. Read the students' numeric grades from the grades_CMP444.txtfile (Figurel) and save them in an array of grades in the course class. The first line contains the course code and the grades are listed in this format: Student ID --- Grade. b. Prompt and allow the user to manage the grades with the following options (Use the Math class methods): 1. Print the course details. 2. Print the grades of students in the course in the following format: Student ID: Letter Grade: NumericValue 3. Compute the average, standard deviation of the grades in the course. 4. Identify the Maximum and Minimum grades in a class.
