Write an application that performs each of the following tasks: a) Specify that class "Pieceworker" inherits from class Employee. b) Create instance variables "Firstname" and "ID" in superclass and a toString to display. C) Add "branch" and toString in Piece Worker. d) Show overriding to display the variables of the subclass. . 02 Draw an inheritance hierarchy for students at a university. Use Student as the superclass of the hierarchy, and then extend Student with classes Undergraduate Student and Graduate Student Continue to extend the hierarchy as deep (i.e., as many levels) as possible. For example, freshman, sophomore, Junior and Senior might extend undergraduate Student, and Doctoral Student and Masters Student might be subclasses of graduate Student. After drawing the hierarchy, discuss the relationships that exist between the classes. Write a program that illustrates the above idea of hierarchy. . I Q1.
