/**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.
