The toString method will returns the first_name, last_name, title, and the monthly pay Finally the calculatePay method will calculate the monthly pay using the following equations monthlyPay = payRate/payScale

Student: The Student class has additional data members gpa and the major. The constructor of the Student will takes the first_name, last_name, phone number and the major as parameters. It sets the gpa to zero. The setGpa method will take the new gpa as a parameter and change the object gpa value. The changeMajor method take the major as a parameter and change the major of the Student object. The toString method will return the first_name, last_name, phone number, major, and the gpa.
