Extend the Person class developed in labl to derive classes for students, hourly employees, and full-time salaried employees. Determine an appropriate class inheritance hierarchy. These class Should have following fields, necessary constructors, and appropriate access and modifier es methods For all employees: . Department Full-time employees: Salary Hourly employees: Hourly rate Number of hours worked each week (4 weeks) Student: . Classes taken and grades for each class (Use an ArrayList) The employee class should contain the necessary methods that will print the total hours (four- week total), average hours per week worked by each employee, and the total wages during a f s during a four week period. The student class should contain the necessary methods to print the transcript for each student
