This module should implement the following functions: • getDonor(donorId): returns a donor by id. • addDonor(donor): adds a donor to the list of donors; donorID should be autoassigned a random number. • updateDonor(donor): updates the donor having the matching donorID. • deleteDonor(donorID): delete the donor with donorID from the list of donors, only if they are not associated with any books. 2.

- Write an application TestStudent that prompts for and reads a student name. It then creates a Student object. It then prompts for and reads the number of quizzes n that the student has taken. It then prompts for and reads the scores of the student in n quizzes and adds each to the totalScore of the student using addQuiz() method. Finally, the application prints the student object using the toString() method, and it also prints his quiz average.

Create a addPizzaSales(enum PizzaType) method. Return different value for different types of pizza. Create it own version of StoreSalesBarChart setDailySales(String salesName). This method should create a PizzaSalesBarChart instance, generate a random pizza type value 10 times and call addPizzaSales for each pizza type value, then return the PizzaSalesBarChart instance.
