Problem 2 Create a superclass named Student The student clas

 Problem 2 Create a superclass named Student. The student class contains name of the student,  midterm grade, a final grade, and the average grade.The average grade is  obtained by adding the midterm grade to the final grade and dividing the result by 2.  Then, create a subclass for students that receive a letter grade. The letter  grade is distributed as follows: 90 and above = A; 80 and above = B; 70  and above = C; 60 and above = D; anything below 50 is F.  Then, create a subclass for students that receive a Pass or Fail grade. Any student that receives a grade of 60 and above passes the class.  Finally, create a test class for the programs above. The test class should  prompt the user to enter a student\'s first name, middle name, last name,  midterm grade, and final grade. The program then calculates the average grade  as speceified in the preceding section.The program should also prompt the  user to enter the category of the student (letter grade or pass/fail).   After the student enters the above information, the program shoud ask  the user if they would like to continue entering information for another student. If the user wishes to continue, the program prompts her/him  again to enter the information specified above otherwise the program stops.  The program then displays the following information for the student(s)  whose information has been entered: First name, Middle name, Last Name,  Category, and Grade.
