Assignment 3 (5%) 
Due Date: (Wednesday) December 26, 2012
Overview:
As specified in the course outline this course will include a semester-long project divided into four parts. In each part you will complete a given a task. In assignment 3, you are asked to make changes in the existing class.
Problem:
Open the class �??Person�?? you created in Assignment2 and modify the class for following issues:
�?� Modify the Person class, which will implement the comparable interface.
�?� Create two subclasses Volunteer and Employee.
�?� In Volunteer class has a variable Volunteerno and override the Grade() method by assigning salary as 0 and print the message �??No salary for the volunteers.�??
�?� In Employee class has a variable Employeeno override the Grade() method by calculating the salary by adding bonus. If the grade is �??A�?? then bonus = 100, �??B�?? then bonus = 50 and �??C�?? then bonus = 25.
�?� Invoke toString() method from these sub classes also which will display both super and sub class details.
�?� Write a Test program to check all above mentioned methods by invoking it. It should display all possible outputs. Also create two objects for Person class and compare these two objects and display which object is greater.
Draw a UML diagram for the above.
You must submit the source code to your teacher by printing the programs from eclipse not from word file. That program should show the results also. Also you will demonstrate your work by running your program in the lab. Also upload the final version of your program in to black board.
Note: Cheating will not be accepted, Marks will be reduced for all the members of that project group based on the percentage of cheating.
