Goals Practice abstract classes & polymorphism Description A college department needs a system for obtaining total hours for all the people involved in its program. They have a record of all the professors, teaching assistants and students with the name of the course and total hours for each course as follows: Professor TA Professor Student Student Student Student Professor TA Student Professor TA Student Student end Isaac Newton Marie Curie Isaac Newton Amy Adams Will Smith Brad Pitt Will Smith Dmitri Mendeleev Carl Gauss Amy Adams Adam Smith Marie Curie Brad Pitt Will Smith Physics 6 Physics 6 Calculus 4 Calculus 4 Calculus 4 Physics 6 Physics 6 Chemistry 6 Calculus 4 Economics 3 Economics 3 Chemistry 6 Chemistry 6 Chemistry 6 Out of all hours for each course, the professor attends only lecture hours, TA conducts lab hours and students must attend all hours. The number of lab and lecture hours is based on the total hours of the course: if total hours > 4 then lab hours = 2, otherwise lab hours = 1 lecture hours = total hours - lab hours. Therefore for the following scenario: Professor TA Student Isaac Newton Marie Curie Brad Pitt Physics 6 Physics 6 Physics 6 the professor has 4 hours, TA has 2, and the student has all 6. Write a program using abstract classes to represent people and a proper class hierarchy to represent professors, TAs and students. The program should scan the full record above all at once and produce a printout of all the people with their total hours through the use of polymorphism. Every person must be mentioned in the printout only once. The printout should be of the following format: Title (Professor/TA/Student) FirstName LastName TotalHours Do not use ArrayList
