Write an application that displays a series of at least 10 student ID numbers (that you have stored in an array) and asks
the user to enter a test letter grade for the student. Create an Exception class named GradeException that contains a static
public array of valid grade letters (‘A’, ‘B’, ‘C’, ‘D’, ‘F’, and ‘I’) you can use to determine whether a grade entered from
the application is valid. In your application, throw a GradeException if the user does not enter a valid letter grade. Catch
the GradeException, and then display an appropriate message. In addition, store an ‘I’ (for Incomplete) for any student for
whom an exception is caught. At the end of the application, display all the student IDs and grades. Save the files as
GradeException.java and TestGrade.java
Input Format
N value as Request
Constraints
1 <= N <= 10
Output Format
Print “Grade Exception” for the grade letter mismatch.
Sample Input
S
Sample Output
Grade Exception
Explanation
If the Student ID Grade letter does not match then print Grade Exception.
