Challenge 1

If any test score in the array is negative or greater than 100, the class should throw an IllegalArgumentException .Demonstrate the class in a program. TestScores Class Custom Exception. Write an exception class named InvalidTestScore . Modify the TestScores class so that it throws an InvalidTestScore exception.

Challenge 2

Write an exception class named InvalidTestScore. Modify the TestScores class you wrote in Exercise 1 so that it throws an InvalidTestScore exception if any of the test scores in the array are invalid.

Test your exception in a program (in a Driver class located in the same file). Your program should prompt the user to enter the number of test scores, and then ask for each test score individually. Then, it should print the average of the test scores.

1 (TestScores Class) + 2 (TestScores Class Custom Exception) + 9 (TestScores Modification for Serialization)

Challenge 9

Modify the TestScores Class that your created in challenge 1 and 2 to be serialized. Write a program that creates an array of at least five TestScore Objects and serializes them. Write another program that deserializes the objects from the file. Comment each line of code between { } brackets.

Only have to do Challenge 9.
