Question

Write an application that displays a series of at least five student ID numbers (that you have stored in an array) and asks the user to enter a numeric test score for the student. Create a ScoreException class, and throw a ScoreException for the class if the user does not enter a valid score (less than or equal to 100 or greater than 0). Catch the ScoreException and then prompt the user to re-enter the score. At the end of the application, display all the student IDs and scores. Save the file as ScoreException.java and TestScore.java.
