Write another client class.

Create an object of class Undergraduate called Alex whose major is CS, gpa is 3.9, credit hours = 54 and honors = true.

Create an object of class Graduate called Mary whose degree is Masters, years = 1, gpa is 4.10, major =computer science and concentration is Cybersecurity.

Print out the Alexs major, gpa, year and use isHonors method to see if the student is an honors student.

Print out the Marys concentration, years spent in grad school and major.

Create an object of class Exchange for an exchange student for Summer 2017 from Brazil and print out his gpa, major and country.
