//////////////////////////////////////////////////////////////////////////////////////////////////

1.)TestScores Class

Write a class named TestScores. The class constructor should accept an array of test scores as its argument. The class should have a method that returns the average of the test scores. If any test score in the array is negative or greater than 100, the class should throw an IllegalArgumentException. Demonstrate the class in the program.

//////////////////////////////////////////////////////////////////////////////////////////////////////

2.) TestScores Class Custom Exception

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

//////////////////////////////////////////////////////////////////////////////////////////////////////

9.) TestScores Modification for Serialization

Modify the TestScores class that you created for Programming Challenge 1 (use TestScores class from challenge 2 as the main question asks) to be serializable. 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.
