JAVA CLASSES/ SUPERCLASS

JAVA CLASSES/ SUPERCLASS

i. Define a class called Student and its two subclasses named underGraduateStudent and postGraduateStudent. Make a subclass of Employee. A person has a name, address, phone number, and email address. A underGraduateStudent has a class status (freshman, sophomore, junior, or senior) while a postGraduateStudent has status(masters, doctorate). Define the status as a constant. Define a method called toString which overridden in each class to display the students name. Write a test program that creates a undergraduate Student and postGraduate and invokes their toString methods.

ii. Define a super class worker. Declare at least three variables and at least two methods. Define another class contractWorker which is a subclass of class employee. Instantiate an object of class contractWorker and show how this object inherits behavior defined in superclass worker.
