Part I:
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 and the program should ask the user to input the number of test scores to be counted, and then each individual test score. It should then make an array of those scores, create a TestScore object, and print the average of the scores. If an IllegalArgumentException is thrown, the main method should catch it, print "Test scores must have a value less than 100 and greater than 0." and terminate the program.
Part II:
Invalid TextScore Write an exception class named Invalid Test Score. Modify the TestScores class you wrote in Part I 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 subclass 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 test scores. If the average method throws an InvalidTestScore exception, the main method should catch it and print "Invalid test score."

Janice usually works on a particular workbook that contains all business related data. she decides to keep a backup of all the data in a separate workbook. she opens a new workbook to transfer the data. which option should she use to copy all the data from one workbook to another workbook?

Your mom wants to purchase a laptop computer. she said she wants her new computer to be able to play her dvds so she can listen to music and wants to know what type of optical drives will play her disk. which type of drive should she look for?

Develop the program incrementally: a) start by reading and displaying each line of the input file to make sure you are reading the data set correctly. b) use the split string method to extract information from each line into a list. print the list to prove that this step is working correctly. d) convert the exam scores to type int and calculate the student’s average. display those items to prove this step is working correctly. e) create a tuple containing the six items for each student (name, exam scores, exam mean). display the tuples to prove this step is working correctly. (optionally, you may want to have the exam scores in a list so your tuple is (name, scores_list, f) append each tuple to a list. display the list to prove this step is working correctly. g) use the sort list method to re-order the tuples in the list. display the list to prove this step is working correctly. h) use a for statement to display the contents of the list as a table (with appropriate formatting). i) use a for statement to calculate the average of all scores on exam #1, then display the results. note that you could have calculated this average within the first loop, but we are explicitly requiring you to do this calculation by looping though your list of tuples. j) add the logic to calculate the average of all scores on exam #2, then display the results.
