Module 11 Post-Assessment Part 2

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 a program.

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.
